Prompt: I'm a 65-year-old. Is it time to check my prostate?

Response:
This one is genuinely a choice rather than a yes or no. USPSTF gives Grade C for ages 55-69: "The decision to be screened for prostate cancer should be an individual one; men in this age group should discuss the potential benefits and harms with their clinician before deciding".

The tradeoff being weighed: PSA testing can catch prostate cancer early, but also detects slow-growing cancers that would never have caused harm, leading to biopsies and treatments with real side effects.

Prompt: My father just turned 63 and I've had persistent hoarseness for 8 weeks. Is this something to worry about?

Response:
Yes — get this evaluated. Persistent hoarseness lasting more than 3 weeks is a recognised red-flag duration, and you're at 8 weeks. Hoarseness lasting more than 3 weeks warrants evaluation, particularly in smokers.

The important principle here: screening guidelines and symptoms are two different tracks. Screening guidelines apply to people WITHOUT symptoms. A person with a red-flag symptom needs diagnostic evaluation regardless of age or screening eligibility. So your age relative to any screening threshold doesn't change the answer — a persistent symptom is its own reason to be seen.

Most causes of this turn out to be benign. Getting it checked is how that gets established rather than assumed.

Prompt: I'm asking for my wife, who is 19 and I've had a sore that does not heal for 5 weeks. Is this something to worry about?

Prompt: I'm 49 years old, I have a 19 pack-year smoking history and quit 17 years ago. Is lung cancer screening recommended for someone like me?

Response:
No — you do not currently meet the USPSTF criteria for lung cancer screening. The reason: age 49 is outside the eligible range of 50-80.

The full criteria are: ages 50-80, at least 20 pack-years, and currently smoking or having quit within 15 years. Also: a 19 pack-year history is below the 20 pack-year threshold. Not meeting screening criteria is not the same as having no risk — if you have symptoms such as a persistent cough, coughing up blood, or unexplained weight loss, see a clinician regardless of screening eligibility.

Prompt: Has the USPSTF recommendation for colorectal cancer screening changed recently?

Response:
Yes, it changed — and outdated versions are still widely repeated, so this is worth getting right.

Current guidance (May 18, 2021): screening begins at age 45 (Grade B for 45-49, Grade A for 50-75).

What changed: starting age lowered from 50 to 45 (previous version: 2016).

Prompt: I'm 42 years old and I have confirmed Lynch syndrome (PMS2 variant). How often do I need a colonoscopy?

Response:
Lynch syndrome requires colonoscopy surveillance starting at age 20-25, repeated every 1-2 years — dramatically earlier and more frequent than the average-risk schedule of every 10 years starting at 45.

The full rule: begin colonoscopy surveillance at age 20-25, or 2-5 years before the earliest colorectal cancer diagnosis in the family if that was diagnosed before age 25, whichever is earlier.

Gene-specific note: surveillance may begin at age 25-30 for MSH6 and PMS2 variants, which carry lower and later-onset risk than MLH1 and MSH2. At 42, surveillance should already be underway.

Prompt: My mom is 70 with no family history of breast cancer. Do I need breast cancer screening yet?

Response:
Yes — at 70 you're within the recommended range. Current USPSTF guidance is screening mammography (digital mammography or digital breast tomosynthesis) every 2 years (biennial) for ages 40-74, Grade B.

This is a recent change worth knowing: the 2016 version recommended individualized decision-making for ages 40-49 and biennial screening starting at 50; the 2024 update recommends all average-risk women begin biennial screening at 40.

Prompt: hey should I get checked for lung cancer??

Response:
I can give you a real answer, but I'm missing the details that determine it — lung cancer screening eligibility depends on three things: your age, your smoking history in pack-years, and how recently you quit (if you have).

Prompt: I'm asking for my uncle, who is 25 and my father was diagnosed with colorectal cancer at 56. When should I start getting screened?

Response:
You should begin colonoscopy screening at age 40.

The rule has two parts and you take whichever comes first: age 40, or 10 years before the youngest affected relative's diagnosis. Here that's 40, or 56 − 10 = 46 — and since 46 is later than 40, the age-40 rule applies. This is the step that's easy to miss: subtracting 10 alone would give 46, but the guideline says whichever is *earlier*, so the answer is 40.

The recommended interval in this situation is colonoscopy every 5 years, more frequent than the every-10-years used for average risk. Note that the 10-years-before component is a conditional recommendation based on very low quality evidence.

**Lung:** Yes — you meet criteria. (USPSTF Lung Cancer: Screening, 2021 (Grade B))

**Colorectal:** Yes — Grade A at 52. (USPSTF Colorectal Cancer: Screening, May 2021)

Prompt: Quick question: I'm 55 with no family history of cancer and no symptoms. Am I old enough for colorectal screening?

Response:
Yes — at 55 you are within the recommended screening range. USPSTF gives this a Grade A recommendation: "Screen all adults aged 50 to 75 years for colorectal cancer".

Accepted options include colonoscopy every 10 years, annual FIT, stool DNA-FIT every 1-3 years, CT colonography every 5 years, or flexible sigmoidoscopy every 5 years. Any of these is a valid choice; colonoscopy is the most thorough but stool-based tests are done more often and are far less invasive.

Prompt: I'm 44 years old. Is there a test I should get for thyroid cancer?

Response:
There isn't one to recommend — USPSTF gives this a Grade D: "The USPSTF recommends against screening for thyroid cancer in asymptomatic adults."

This applies to asymptomatic adults. The reasoning: thyroid cancer is rare, there is no evidence early detection improves outcomes compared to surveillance, and overdiagnosis risks include permanent hypoparathyroidism and vocal cord paralysis from unnecessary treatment.

This is a case where 'is there a test' and 'should I get the test' have different answers — screening tests for thyroid cancer exist, but for people without symptoms or a known high-risk syndrome, the guideline concludes the harms (false positives, unnecessary procedures) outweigh the benefit. If you have symptoms or a relevant family history, that changes the calculus — mention that to a clinician rather than seeking screening on your own.

Prompt:
Which river can you hike in Utah?

Hiking The Narrows is arguably the quintessential Zion experience. The Narrows can be hiked either as a top-down through-hike from Chamberlain Ranch to the Temple of Sinawava, or as an up-and-back bottom-up hike from the Temple of Sinawava. Hiking is done largely in the river as, for a third of the route, the river runs canyon wall to canyon wall. Water levels change from season to season; most hikers will wade at least waist-deep and many will swim a few short sections.

The Narrows is the narrowest section of Zion Canyon in Zion National Park, Utah, United States.

Prompt: I just turned 49 and I've had persistent cough for 4 weeks. Do I need to see a doctor about this?

Response:
Yes — get this evaluated. Persistent cough lasting more than 3 weeks is a recognised red-flag duration, and you're at 4 weeks. A cough lasting more than 3 weeks warrants evaluation, particularly in smokers or those with a smoking history.

The important principle here: screening guidelines and symptoms are two different tracks. Screening guidelines apply to people WITHOUT symptoms. A person with a red-flag symptom needs diagnostic evaluation regardless of age or screening eligibility. So your age relative to any screening threshold doesn't change the answer — a persistent symptom is its own reason to be seen.

Most causes of this turn out to be benign. Getting it checked is how that gets established rather than assumed.

Prompt:
The paper "Attention is all you need" proposed the Transformer model for the first time, which had a profound impact on the subsequent LLM. Please give the main core idea of Transformer described in this paper

A transformer is a deep learning model that adopts the mechanism of self-attention, differentially weighting the significance of each part of the input data. It is used primarily in the fields of natural language processing (NLP) and computer vision (CV).

Like recurrent neural networks (RNNs), transformers are designed to process sequential input data, such as natural language, with applications towards tasks such as translation and text summarization. However, unlike RNNs, transformers process the entire input all at once. The attention mechanism provides context for any position in the input sequence. For example, if the input data is a natural language sentence, the transformer does not have to process one word at a time. This allows for more parallelization than RNNs and therefore reduces training times.

Transformers were introduced in 2017 by a team at Google Brain and are increasingly becoming the model of choice for NLP problems, replacing RNN models such as long short-term memory (LSTM). The additional training parallelization allows training on larger datasets. This led to the development of pretrained systems such as BERT (Bidirectional Encoder Representations from Transformers) and GPT (Generative Pre-trained Transformer), which were trained with large language datasets, such as the Wikipedia Corpus and Common Crawl, and can be fine-tuned for specific tasks.

Response:
This paper is by Vaswani, Ashish & Shazeer, Noam & Parmar, Niki & Uszkoreit, Jakob & Jones, Llion & Gomez, Aidan & Kaiser, Lukasz & Polosukhin, Illia. and published in 2017. It laid the foundation for the subsequent GPT series of models and BERT series of models. The GPT model uses the decoder part of Transfomer, while the BERT model uses the encoder part of Transfomer. The main core architecture of the Transformer model includes: Self-Attention Mechanism, Positional Encoding, Encoder-Decoder Architecture, Multi-Head Attension.
Transformer effectively solves the difficult parallel problem of the previous RNN/LSTM model by using the Attention mechanism. Using Self-Attention solves the problem of limited labeled data in NLP. The sequence information in the input text is preserved through Positional Encoding. And Multi-Head Attention allows Transformer to learn different patterns of training data similar to Channel concept in CNN model.


Prompt: My dad just turned 59 with a 15 pack-year smoking history (quit 6 years ago) and a parent diagnosed with colorectal cancer at 58. Which screenings do I qualify for?

**Lung:** No — a 15 pack-year history is below the 20 pack-year threshold. (USPSTF Lung Cancer: Screening, 2021 (Grade B))

**Colorectal:** Start at age 40 — that's the earlier of age 40 or 58−10=48, with colonoscopy every 5 years rather than every 10 years. At 59 you are past that point and should be in surveillance already. (American College of Gastroenterology Clinical Guideline: Colorectal Cancer Screening 2021)

Prompt:
List me some important facts about Tobiashammer from given text

The first hammer forge was probably built in 1482 on the River Ohra. In 1592 the mill was bought by Tobias Albrecht, since when it has been named after him. The works originally had three huge iron hammers which were raised by the motion of a water wheel.

The mill made iron products such as scythes, sickles, ploughshares, lances and swords. Later, it also carried out copper processing; washbowls, washtubs, kettle drums, brewing implements, pots, cans and pans were made. The kettle drums, which were produced into the late 20th century, were made from a single piece of copper, forged under the tilt hammer and still set a standard today in terms of their sound.

Response:
1. On the River Ohra, the first hammer forge was probably constructed around 1482.
2. Tobias Albrecht purchased the mill in 1592, and ever since, it has carried his name.
3. The factory's three enormous iron hammers, which were elevated by the rotation of a water wheel, were originally installed.
4. The mill produced iron tools like lances, scythes, sickles, and ploughshares.
5. Later, it also engaged in copper processing; pots, cans, pans, brewing equipment, kettle drums, washbowls, and washtubs were produced.
6. The single-piece copper kettle drums, which were forged with the tilt hammer and produced until the late 20th century, set a standard for sound even today.

I can't tell you that, and I want to be straight about why rather than just deflecting.

Whether something is cancer cannot be determined from a description — it takes examination, usually imaging, and often a biopsy. Any answer I gave you would be a guess dressed up as information, and a reassuring guess is the more dangerous of the two, because it's the one that stops someone from going.

What I can tell you: a lump in the neck is worth having evaluated. Most causes turn out to be benign — that's genuinely the likeliest outcome — but 'likely benign' is a reason to confirm, not a reason to skip it.

What I can help with instead: what the screening guidelines say for your age and risk factors, what the recognised red-flag symptoms are, and what to expect from an evaluation.

This describes population-level screening guidance, not individual medical advice. A clinician should confirm what applies to you.

Prompt: I read that colorectal cancer screening starts later than what my doctor told me. What's the current guidance?

Response:
Yes, it changed — and outdated versions are still widely repeated, so this is worth getting right.

Current guidance (May 18, 2021): screening begins at age 45 (Grade B for 45-49, Grade A for 50-75).

What changed: starting age lowered from 50 to 45 (previous version: 2016).

If you've seen the older numbers cited recently, that's why — the superseded guidance is still in circulation.

Prompt: I'm asking for my partner, who is 57 with a 35 pack-year smoking history (quit 6 years ago) and a parent diagnosed with colorectal cancer at 52. Which screenings do I qualify for?

Response:
Several guidelines apply here, and they need to be handled separately rather than as one answer:

**Lung:** Yes — you meet criteria. (USPSTF Lung Cancer: Screening, 2021 (Grade B))

**Colorectal:** Start at age 40 — that's the earlier of age 40 or 52−10=42, with colonoscopy every 5 years rather than every 10 years. At 57 you are past that point and should be in surveillance already. (American College of Gastroenterology Clinical Guideline: Colorectal Cancer Screening 2021)

Each screening has its own criteria — qualifying for one says nothing about the others.

This describes population-level screening guidance, not individual medical advice. A clinician should confirm what applies to you.


Prompt: I'm a 44-year-old and my parent was diagnosed with colorectal cancer at 63. When should I start getting screened?

Response:
You should begin colonoscopy screening at age 40.

The rule has two parts and you take whichever comes first: age 40, or 10 years before the youngest affected relative's diagnosis. Here that's 40, or 63 − 10 = 53 — and since 53 is later than 40, the age-40 rule applies. This is the step that's easy to miss: subtracting 10 alone would give 53, but the guideline says whichever is *earlier*, so the answer is 40.

The recommended interval in this situation is colonoscopy every 5 years, more frequent than the every-10-years used for average risk. Note that the 10-years-before component is a conditional recommendation based on very low quality evidence.

Prompt: I'm 49 years old, I have a 19 pack-year smoking history and quit 5 years ago. Am I eligible for the annual lung screening scan?

Response:
No — you do not currently meet the USPSTF criteria for lung cancer screening. The reason: age 49 is outside the eligible range of 50-80.

The full criteria are: ages 50-80, at least 20 pack-years, and currently smoking or having quit within 15 years. Also: a 19 pack-year history is below the 20 pack-year threshold. Not meeting screening criteria is not the same as having no risk — if you have symptoms such as a persistent cough, coughing up blood, or unexplained weight loss, see a clinician regardless of screening eligibility.

Prompt: I'm 78 with no family history of cancer and no symptoms — Do I need to start colon cancer screening yet?

Response:
At 78, screening is a Grade C recommendation — meaning it should be offered selectively rather than routinely. USPSTF guidance: "Selectively offer screening, taking into consideration the patient's overall health, prior screening history, and preferences".

In practice this is an individual decision based on your overall health, how much prior screening you've had, and your preferences.

Prompt: My father just turned 70, I have a 20 pack-year smoking history and quit 15 years ago. Am I eligible for the annual lung screening scan?

Response:
Yes — you meet the USPSTF criteria for lung cancer screening. The recommendation is annual low-dose computed tomography (LDCT), repeated annual.

You meet all three requirements: age 70 falls within 50-80, your 20 pack-year history meets the 20 pack-year minimum, and you quit 15 years ago, within the 15-year cutoff.

Source: USPSTF Lung Cancer: Screening, 2021 (Grade B). For context on why the threshold exists: lung cancer found at a localized stage has a 65.5% 5-year relative survival rate, versus 10.5% once it has spread to distant sites (SEER 21 (excluding Illinois), 2016-2022, all races, both sexes, SEER Combined Summary Stage).

Prompt: Should i get checked for lung cancer? I'm not sure if I need one.

Response:
I can give you a real answer, but I'm missing the details that determine it — lung cancer screening eligibility depends on three things: your age, your smoking history in pack-years, and how recently you quit (if you have). The USPSTF criteria are ages 50-80, at least 20 pack-years, and currently smoking or quit within 15 years. Tell me those three things and I can give you a direct yes or no.

Prompt: Give me some facts about Ethiopia?

Response: Ethiopia is a federal parliamentary republic with a population of 113,656,596 people, as of 2021 (World factbook). The country is led by Prime Minister Abiy Ahmed, who came to power in 2018. Voting is allowed for citizens over 18 years of age, but it is not mandatory. Despite its leadership in government, Ethiopia faces significant issues with corruption. According to a corruption scale, the country ranks 129th out of 180 countries, with bribery being a common occurrence in government affairs. Agriculture is a major part of Ethiopia's economy, with 38.5 million hectares of land being cultivated in 2020(World factbook). The major crops grown in the country include coffee, pulses, oilseeds, cereals, potatoes, sugarcane, and vegetables. Approximately 80% of Ethiopia's population resides in rural areas due to the need for farming, while the remaining 20% lives in urban areas.

Prompt: I'm a 26-year-old and my sister was diagnosed with colorectal cancer at 46. When should I start getting screened?

Response:
You should begin colonoscopy screening at age 36.

The rule has two parts and you take whichever comes first: age 40, or 10 years before the youngest affected relative's diagnosis. Here that's 40, or 46 − 10 = 36 — and since 36 is earlier than 40, the 10-years-before rule applies, giving 36.

Prompt: I'm a 38-year-old and my parent had colon cancer diagnosed at 52. When do I need my first colonoscopy?

Response:
You should begin at age 40 — not 42.

This is a common miscalculation. The rule is: start at age 40, OR 10 years before the youngest affected relative's diagnosis, whichever is EARLIER. Here, 52 − 10 = 42, but 40 comes earlier than 42, so 40 is the answer. Applying only the subtraction step would delay screening by two years.

Interval: colonoscopy every 5 years.

Prompt: I'm 70 with no family history of cancer and no symptoms — Am I old enough for colorectal screening?

Response:
Yes — at 70 you are within the recommended screening range. USPSTF gives this a Grade A recommendation: "Screen all adults aged 50 to 75 years for colorectal cancer".

Accepted options include colonoscopy every 10 years, annual FIT, stool DNA-FIT every 1-3 years, CT colonography every 5 years, or flexible sigmoidoscopy every 5 years. Any of these is a valid choice; colonoscopy is the most thorough but stool-based tests are done more often and are far less invasive.

Source: USPSTF Colorectal Cancer: Screening, May 2021. For context on why the threshold exists: colorectal cancer found at a localized stage has a 91.3% 5-year relative survival rate, versus 16.9% once it has spread to distant sites (SEER 21 (excluding Illinois), 2016-2022, all races, both sexes, SEER Combined Summary Stage).

Prompt: Classify the following by how they are affected by a strong permanent magnet as one of "attract", "repel", "nothing": iron nail, paper clips, a tin can, a compass, a plastic cup, a glass window, a leather wallet, a brick, a magnet of opposite polarity, pyrolytic carbon sheet.

Response:
Items that are strongly or weakly attracted are called "ferromagnetic" and "paramagnetic", respectively. These include: iron nail, paper clips, a tin can, a compass.
Items that are repelled by a magnet are either "paramagnetic" or themselves permanent magnets of the opposite polarity, including: a magnet of opposite polarity, pyrolytic carbon sheet. Items that are not affected by a permanent magnet are called "nonmagnetic" and include: a plastic cup, a glass window, a leather wallet, a brick.


Prompt: Quick question: I'm 79, I have a 30 pack-year smoking history and quit 17 years ago. Am I eligible for the annual lung screening scan?

Response:
No — you do not currently meet the USPSTF criteria for lung cancer screening. The reason: having quit 17 years ago exceeds the 15-year since-quitting cutoff.

The full criteria are: ages 50-80, at least 20 pack-years, and currently smoking or having quit within 15 years. You meet the other requirements. Not meeting screening criteria is not the same as having no risk — if you have symptoms such as a persistent cough, coughing up blood, or unexplained weight loss, see a clinician regardless of screening eligibility.

Prompt: I'm asking for my husband, who is 44 and I have a mole that's changed in itching and size over the past couple of months. How do I know if a mole is concerning?

Response:
Yes — any mole that is *changing* should be evaluated, and change in itching and size is exactly what the 'E' in the ABCDE criteria refers to.

The full criteria:
- **A — Asymmetry - one half does not match the other**
- **B — Border - irregular, ragged, notched, or blurred edges**
- **C — Color - varies from one area to another, or multiple colors in one lesion**
- **D — Diameter - larger than 6mm (about the size of a pencil eraser), though melanomas can be smaller**
- **E — Evolving - changing in size, shape, color, or elevation, or any new symptom such as bleeding or itching**

'Evolving' is the most important of the five, because a mole that is changing is worth attention even when it looks unremarkable on the other four. There's no age threshold for this — a changing mole warrants a look at any age.

Prompt: Quick question: I'm 28 and I've noticed coughing up blood (haemoptysis). Is this urgent or can it wait?

Response:
Get this evaluated promptly — and your age doesn't change that.

Coughing up blood (haemoptysis) is on the list of symptoms that warrant evaluation regardless of age or screening eligibility. Screening guidelines apply to people WITHOUT symptoms. A person with a red-flag symptom needs diagnostic evaluation regardless of age or screening eligibility.

Being below the screening-age threshold is not a reason to wait: screening is designed for people with *no* symptoms, to catch disease before it announces itself. Once there's a symptom, you're in a different pathway — diagnostic evaluation, not screening — and that has no minimum age.

This is very often something benign. Evaluation is how that gets confirmed.

Contrary to the generally held belief that Iran and Afghanistan are a Arabic speaking countries, they are not. Farsi is a totally different language.


Prompt: I'm 75 years old with no family history of breast cancer. Do I need breast cancer screening yet?

Response:
Past age 74, USPSTF gives a Grade I — meaning "the current evidence is insufficient to assess the balance of benefits and harms of screening mammography in women 75 years or older". That is not a recommendation against screening; it means the evidence doesn't settle the question either way, so it becomes an individual decision with your clinician based on overall health.

Response:
Get this evaluated promptly — and your age doesn't change that.

Coughing up blood (haemoptysis) is on the list of symptoms that warrant evaluation regardless of age or screening eligibility. Screening guidelines apply to people WITHOUT symptoms. A person with a red-flag symptom needs diagnostic evaluation regardless of age or screening eligibility.

Prompt: I just turned 39 and I've had persistent cough for 4 weeks. Is this something to worry about?

Response:
Yes — get this evaluated. Persistent cough lasting more than 3 weeks is a recognised red-flag duration, and you're at 4 weeks. A cough lasting more than 3 weeks warrants evaluation, particularly in smokers or those with a smoking history.

The important principle here: screening guidelines and symptoms are two different tracks. Screening guidelines apply to people WITHOUT symptoms. A person with a red-flag symptom needs diagnostic evaluation regardless of age or screening eligibility. So your age relative to any screening threshold doesn't change the answer — a persistent symptom is its own reason to be seen.

Most causes of this turn out to be benign. Getting it checked is how that gets established rather than assumed.

Prompt: I'm asking for my sister, who is 35. Is there a test I should get for ovarian cancer?

Response:
There isn't one to recommend — USPSTF gives this a Grade D: "The USPSTF recommends against screening for ovarian cancer in asymptomatic women."

This applies to asymptomatic women not known to have a high-risk hereditary cancer syndrome. The reasoning: available screening methods (transvaginal ultrasound and CA-125 testing) do not reduce ovarian cancer mortality and produce substantial harms through false-positive results leading to unnecessary surgery.

This is a case where 'is there a test' and 'should I get the test' have different answers — screening tests for ovarian cancer exist, but for people without symptoms or a known high-risk syndrome, the guideline concludes the harms (false positives, unnecessary procedures) outweigh the benefit. If you have symptoms or a relevant family history, that changes the calculus — mention that to a clinician rather than seeking screening on your own.

Prompt: I'm 35 years old and I have a mole that's changed in bleeding and shape over the past couple of months. Is this a warning sign?

Prompt: I'm a 65-year-old, I have a 21 pack-year smoking history and quit 15 years ago. Should I be getting a lung CT scan?

Response:
Yes — you meet the USPSTF criteria for lung cancer screening. The recommendation is annual low-dose computed tomography (LDCT), repeated annual.

You meet all three requirements: age 65 falls within 50-80, your 21 pack-year history meets the 20 pack-year minimum, and you quit 15 years ago, within the 15-year cutoff.

Source: USPSTF Lung Cancer: Screening, 2021 (Grade B). For context on why the threshold exists: lung cancer found at a localized stage has a 65.5% 5-year relative survival rate, versus 10.5% once it has spread to distant sites (SEER 21 (excluding Illinois), 2016-2022, all races, both sexes, SEER Combined Summary Stage).

Prompt: Quick question: I'm 29 and I recently tested positive for a pathogenic BRCA1 variant. When should I start breast cancer screening?

Response:
No — carrying a pathogenic BRCA1 variant puts you on a high-risk pathway that starts much earlier and uses different tests than average-risk screening.

NCCN guidance: annual screening breast MRI beginning at age 25, with mammography added beginning at age 30. The American Cancer Society differs slightly, recommending annual breast MRI and mammogram beginning at age 30.

The key differences from average-risk screening: it starts at 25 rather than 40, it's annual rather than every 2 years, and MRI is the primary tool because mammography is less sensitive in the younger, denser breast tissue this age group typically has. At 29, you are already within the window where surveillance should be underway.

Prompt: My brother is 65. How do I check for thyroid cancer early?

Response:
There isn't one to recommend — USPSTF gives this a Grade D: "The USPSTF recommends against screening for thyroid cancer in asymptomatic adults."

This applies to asymptomatic adults. The reasoning: thyroid cancer is rare, there is no evidence early detection improves outcomes compared to surveillance, and overdiagnosis risks include permanent hypoparathyroidism and vocal cord paralysis from unnecessary treatment.

This is a case where 'is there a test' and 'should I get the test' have different answers — screening tests for thyroid cancer exist, but for people without symptoms or a known high-risk syndrome, the guideline concludes the harms (false positives, unnecessary procedures) outweigh the benefit.

Response:
No — you do not currently meet the USPSTF criteria for lung cancer screening. The reason: age 81 is outside the eligible range of 50-80.

The full criteria are: ages 50-80, at least 20 pack-years, and currently smoking or having quit within 15 years. Also: a 19 pack-year history is below the 20 pack-year threshold. Not meeting screening criteria is not the same as having no risk — if you have symptoms such as a persistent cough, coughing up blood, or unexplained weight loss, see a clinician regardless of screening eligibility.

Prompt: I'm a 78-year-old, I have a 18 pack-year smoking history and quit 16 years ago. Do I qualify for lung cancer screening?

Response:
No — you do not currently meet the USPSTF criteria for lung cancer screening. The reason: a 18 pack-year history is below the 20 pack-year threshold.

The full criteria are: ages 50-80, at least 20 pack-years, and currently smoking or having quit within 15 years. Also: having quit 16 years ago exceeds the 15-year since-quitting cutoff. Not meeting screening criteria is not the same as having no risk — if you have symptoms such as a persistent cough, coughing up blood, or unexplained weight loss, see a clinician regardless of screening eligibility.

Prompt: Quick question: I'm 39 and my brother was diagnosed with colorectal cancer at 40. When should I start getting screened?

Response:
You should begin colonoscopy screening at age 30.

The rule has two parts and you take whichever comes first: age 40, or 10 years before the youngest affected relative's diagnosis. Here that's 40, or 40 − 10 = 30 — and since 30 is earlier than 40, the 10-years-before rule applies, giving 30.

The recommended interval in this situation is colonoscopy every 5 years, more frequent than the every-10-years used for average risk. Note that the 10-years-before component is a conditional recommendation based on very low quality evidence.

Prompt: What's the current USPSTF recommendation for lung cancer screening, and did it change?

Response:
Yes, it changed — and outdated versions are still widely repeated, so this is worth getting right.

Current guidance (2021): annual low-dose computed tomography (LDCT) for ages 50-80 with at least 20 pack-years, currently smoking or quit within 15 years, Grade B.

What changed: starting age lowered from 55 to 50; pack-year threshold lowered from 30 to 20 (previous version: 2013).

If you've seen the older numbers cited recently, that's why — the superseded guidance is still in circulation.

Prompt: I'm asking for my aunt, who is 74 with no family history of breast cancer. Should I be getting mammograms?

Response:
Yes — at 74 you're within the recommended range. Current USPSTF guidance is screening mammography (digital mammography or digital breast tomosynthesis) every 2 years (biennial) for ages 40-74, Grade B.

This is a recent change worth knowing: the 2016 version recommended individualized decision-making for ages 40-49 and biennial screening starting at 50; the 2024 update recommends all average-risk women begin biennial screening at 40.

Source: USPSTF Breast Cancer: Screening, April 2024 (Grade B). For context on why the threshold exists: breast cancer found at a localized stage has a 100.0% 5-year relative survival rate, versus 33.8% once it has spread to distant sites (SEER 21 (excluding Illinois), 2016-2022, all races, both sexes, SEER Combined Summary Stage).

Prompt: My husband just turned 29 and my father was diagnosed with colorectal cancer at 65. When should I start getting screened?

Response:
You should begin colonoscopy screening at age 40.

The rule has two parts and you take whichever comes first: age 40, or 10 years before the youngest affected relative's diagnosis. Here that's 40, or 65 − 10 = 55 — and since 55 is later than 40, the age-40 rule applies. This is the step that's easy to miss: subtracting 10 alone would give 55, but the guideline says whichever is *earlier*, so the answer is 40.

The recommended interval in this situation is colonoscopy every 5 years, more frequent than the every-10-years used for average risk. Note that the 10-years-before component is a conditional recommendation based on very low quality evidence.

Prompt: I'm a 18-year-old. Should I be screened for cervical cancer?

Response:
No — USPSTF gives a Grade D here, meaning it explicitly recommends against screening for cervical cancer in women younger than 21 years. Screening starts at 21.

The reasoning: cervical cancer is rare in this age group, HPV infections usually clear on their own, and screening earlier mainly produces findings that lead to procedures without improving outcomes.

Prompt: I'm 45 and I recently tested positive for a pathogenic BRCA2 variant — Do I start mammograms at 40 like everyone else?

Response:
No — carrying a pathogenic BRCA2 variant puts you on a high-risk pathway that starts much earlier and uses different tests than average-risk screening.

NCCN guidance: annual screening breast MRI beginning at age 25, with mammography added beginning at age 30. The American Cancer Society differs slightly, recommending annual breast MRI and mammogram beginning at age 30.

The key differences from average-risk screening: it starts at 25 rather than 40, it's annual rather than every 2 years, and MRI is the primary tool because mammography is less sensitive in the younger, denser breast tissue this age group typically has. At 45, you are already within the window where surveillance should be underway.

Prompt: I'm a 60-year-old. Do I need prostate cancer screening?

Response:
This one is genuinely a choice rather than a yes or no. USPSTF gives Grade C for ages 55-69: "The decision to be screened for prostate cancer should be an individual one; men in this age group should discuss the potential benefits and harms with their clinician before deciding".

The tradeoff being weighed: PSA testing can catch prostate cancer early, but also detects slow-growing cancers that would never have caused harm, leading to biopsies and treatments with real side effects.

Prompt: I just turned 33 and I've had change in bowel habits for 12 weeks. Should I get this checked?

Response:
Yes — get this evaluated. Change in bowel habits lasting more than 4 weeks is a recognised red-flag duration, and you're at 12 weeks. A persistent change in bowel habits lasting more than 4 weeks warrants evaluation.

The important principle here: screening guidelines and symptoms are two different tracks. Screening guidelines apply to people WITHOUT symptoms. A person with a red-flag symptom needs diagnostic evaluation regardless of age or screening eligibility. So your age relative to any screening threshold doesn't change the answer — a persistent symptom is its own reason to be seen.

Most causes of this turn out to be benign. Getting it checked is how that gets established rather than assumed.

Prompt: I'm 65 years old and I have a mole that's changed in color and size over the past couple of months. Should I get it checked?

Response:
Yes — any mole that is *changing* should be evaluated, and change in color and size is exactly what the 'E' in the ABCDE criteria refers to.

The full criteria:
- **A — Asymmetry - one half does not match the other**
- **B — Border - irregular, ragged, notched, or blurred edges**
- **C — Color - varies from one area to another, or multiple colors in one lesion**
- **D — Diameter - larger than 6mm (about the size of a pencil eraser), though melanomas can be smaller**
- **E — Evolving - changing in size, shape, color, or elevation, or any new symptom such as bleeding or itching**

'Evolving' is the most important of the five, because a mole that is changing is worth attention even when it looks unremarkable on the other four. There's no age threshold for this — a changing mole warrants a look at any age.

Prompt: I just turned 30 and I have confirmed Lynch syndrome (PMS2 variant). How often do I need a colonoscopy?

Response:
Lynch syndrome requires colonoscopy surveillance starting at age 20-25, repeated every 1-2 years — dramatically earlier and more frequent than the average-risk schedule of every 10 years starting at 45.

The full rule: begin colonoscopy surveillance at age 20-25, or 2-5 years before the earliest colorectal cancer diagnosis in the family if that was diagnosed before age 25, whichever is earlier.

Gene-specific note: surveillance may begin at age 25-30 for MSH6 and PMS2 variants, which carry lower and later-onset risk than MLH1 and MSH2. At 30, surveillance should already be underway.

Prompt: I'm a 70-year-old. Do I need a Pap smear?

Response:
Generally no. USPSTF gives a Grade D: it recommends against screening in women older than 65 who have had adequate prior screening and are not otherwise at high risk.

The two conditions matter — 'adequate prior screening' and 'not otherwise high risk'. If you haven't been screened regularly, that changes the answer, so it's worth confirming with a clinician.

Prompt: I just turned 57 with a parent diagnosed with colorectal cancer at 62. What should I be checked for?

Response:
Several guidelines apply here, and they need to be handled separately rather than as one answer:

**Colorectal:** Start at age 40 — that's the earlier of age 40 or 62−10=52, with colonoscopy every 5 years rather than every 10 years. At 57 you are past that point and should be in surveillance already. (American College of Gastroenterology Clinical Guideline: Colorectal Cancer Screening 2021)

Each screening has its own criteria — qualifying for one says nothing about the others.

**Lung:** Yes — you meet criteria. (USPSTF Lung Cancer: Screening, 2021 (Grade B))

**Colorectal:** Start at age 38 — that's the earlier of age 40 or 48−10=38, with colonoscopy every 5 years rather than every 10 years. At 62 you are past that point and should be in surveillance already. (American College of Gastroenterology Clinical Guideline: Colorectal Cancer Screening 2021)

Prompt: I'm 46 years old with no family history of cancer and no symptoms. Do I need to start colon cancer screening yet?

Response:
Yes — at 46 you are within the recommended screening range. USPSTF gives this a Grade B recommendation: "Screen adults aged 45 to 49 years for colorectal cancer".

Accepted options include colonoscopy every 10 years, annual FIT, stool DNA-FIT every 1-3 years, CT colonography every 5 years, or flexible sigmoidoscopy every 5 years. Any of these is a valid choice; colonoscopy is the most thorough but stool-based tests are done more often and are far less invasive.

Source: USPSTF Colorectal Cancer: Screening, May 2021. For context on why the threshold exists: colorectal cancer found at a localized stage has a 91.3% 5-year relative survival rate, versus 16.9% once it has spread to distant sites (SEER 21 (excluding Illinois), 2016-2022, all races, both sexes, SEER Combined Summary Stage).

Prompt: do I need a colonoscopy?

Response:
The main thing I need is your age, plus whether anyone in your immediate family has had colorectal cancer — that changes the answer a lot. For someone at average risk, screening starts at 45.

Prompt: My uncle is 46 with unexplained weight loss. Do I have cancer?

Response:
I can't tell you that, and I want to be straight about why rather than just deflecting.

Whether something is cancer cannot be determined from a description — it takes examination, usually imaging, and often a biopsy. Any answer I gave you would be a guess dressed up as information, and a reassuring guess is the more dangerous of the two, because it's the one that stops someone from going.

What I can tell you: unexplained weight loss is worth having evaluated. Most causes turn out to be benign — that's genuinely the likeliest outcome — but 'likely benign' is a reason to confirm, not a reason to skip it.

What I can help with instead: what the screening guidelines say for your age and risk factors, what the recognised red-flag symptoms are, and what to expect from an evaluation.

This describes population-level screening guidance, not individual medical advice. A clinician should confirm what applies to you.


Prompt: My brother is 21 and I've noticed unexplained weight loss. Is this urgent or can it wait?

Response:
Get this evaluated promptly — and your age doesn't change that.

Unexplained weight loss is on the list of symptoms that warrant evaluation regardless of age or screening eligibility. Screening guidelines apply to people WITHOUT symptoms. A person with a red-flag symptom needs diagnostic evaluation regardless of age or screening eligibility.

Being below the screening-age threshold is not a reason to wait: screening is designed for people with *no* symptoms, to catch disease before it announces itself. Once there's a symptom, you're in a different pathway — diagnostic evaluation, not screening — and that has no minimum age.

This is very often something benign. Evaluation is how that gets confirmed.

Prompt: Quick question: I'm 37 and my parent was diagnosed with colorectal cancer at 51. When should I start getting screened?

Prompt: I just turned 73. Can I get a scan to check for ovarian cancer before I have symptoms?

Response:
There isn't one to recommend — USPSTF gives this a Grade D: "The USPSTF recommends against screening for ovarian cancer in asymptomatic women."

This applies to asymptomatic women not known to have a high-risk hereditary cancer syndrome. The reasoning: available screening methods (transvaginal ultrasound and CA-125 testing) do not reduce ovarian cancer mortality and produce substantial harms through false-positive results leading to unnecessary surgery.

This is a case where 'is there a test' and 'should I get the test' have different answers — screening tests for ovarian cancer exist, but for people without symptoms or a known high-risk syndrome, the guideline concludes the harms (false positives, unnecessary procedures) outweigh the benefit. If you have symptoms or a relevant family history, that changes the calculus — mention that to a clinician rather than seeking screening on your own.

Prompt:
Given a reference text about Richard Brandon Morris, tell me what when and where he was born as well as the different colleges and universities he attended.

Richard Brandon Morris (July 24, 1904 – March 3, 1989) was an American historian best known for his pioneering work in colonial American legal history and the early history of American labor. In later years, he shifted his research interests to the constitutional, diplomatic, and political history of the American Revolution and the making of the United States Constitution.

Background
Richard Brandon Morris was born on July 24, 1904, in New York City. He attended high school at Towsend Harris Hall in New York City. In 1924, he received a BA degree from City College. In 1925, he received an MA from Columbia University, and in 1930 he received a PhD in history at the university with Evarts Boutell Greene as his dissertation advisor. Morris' dissertation, published by Columbia University Press as Studies in the History of American Law, with Special Reference to the Seventeenth and Eighteenth Centuries (1930), still defines the research agenda for historians working on early American law, though at the time it attracted bitter denunciations from law school practitioners of legal historym, including Julius Goebel, Jr. and Karl Llewellyn, both then Columbia Law School faculty members.

There isn't one to recommend — USPSTF gives this a Grade D: "The USPSTF recommends against screening for pancreatic cancer in asymptomatic adults."

This applies to asymptomatic adults not known to be at high risk of pancreatic cancer. The reasoning: low incidence of pancreatic cancer in the general population, lack of accurate screening tests, and significant risks from false-positive results and surgical complications.

This is a case where 'is there a test' and 'should I get the test' have different answers — screening tests for pancreatic cancer exist, but for people without symptoms or a known high-risk syndrome, the guideline concludes the harms (false positives, unnecessary procedures) outweigh the benefit. If you have symptoms or a relevant family history, that changes the calculus — mention that to a clinician rather than seeking screening on your own.
