The simple version
Here is a friendly checklist of habits linked with lower cancer risk. You do not have to do it all. Pick what feels doable and start small. Every step supports your health.
Small changes count. Start with one thing.
Move and maintain
Habits linked with lower risk:
- Move most days. The National Cancer Institute cites 150 to 300 minutes a week of moderate-intensity activity for adults. Build up slowly.
- Sit less. NCI says long periods of sitting are a risk factor for many chronic conditions and may be linked to cancer risk, though that research is more limited.
- Work toward a healthy weight, or keep the one you have. Be kind and realistic about it.
Eat and drink
Gentle choices, with nothing off limits:
- Eat a varied diet with vegetables, fruits, whole grains, and beans. These support general health. NCI says it is not known whether such a diet lowers colorectal cancer risk.
- NCI says some studies suggest a diet high in red meat raises colorectal cancer risk, though results vary.
- Alcohol is linked to higher risk of several cancers, including mouth, throat, esophagus, and breast. Ask your care team if you want help cutting back.
Protect and prevent
Other steps that help:
- Do not smoke. Ask for help quitting if you do.
- Protect your skin from the sun.
- Get vaccines when they apply to you, such as HPV and hepatitis B.
- Ask your doctor which screenings are right for you.
A kind reminder
This checklist is about giving yourself the best chance and feeling your best. It is not about blame or fear. Cancer can happen even when someone does everything 'right,' and it is never a person's fault.
Movement and healthy habits are not a cure, but they can support your health.

Common questions
How do I use this checklist?
Skim it, pick one or two things that feel doable, and start there. It's a gentle guide, not a test. Small, steady changes support your health more than trying to be perfect all at once.
Do I need to do everything on it?
No. Every item is linked with lower risk, but you don't have to do them all. Improving in any area helps, and progress counts more than perfection.
What about screening?
Screening tests can find some cancers early, or find changes before they become cancer. The right tests depend on your age, sex, family history, and risk — so ask your doctor which screenings are right for you and when.
Does following this guarantee I won't get cancer?
No. These habits lower risk and support health, but cancer can still happen. It is never a person's fault, and this checklist is about giving yourself the best chance and feeling well.

Review details and limits
Cancer Explained does not originate medical claims. Every page restates guidance already published by the National Cancer Institute, the CDC, the USPSTF and the FDA, in plain language, with the source cited so you can check the original yourself. AI does the translating and organizing; automated checks test claims, citations, clarity and safety before anything publishes, and this is translation and navigation, not clinical judgment. Nothing here is personal medical advice, and no page can account for your particular situation.
Editorial status — Source checked. This page was written with AI assistance and then compared with the sources listed on it, looking for statements those sources do not back up. That check is not a sentence-by-sentence record and can miss errors. It is not a medical review, and it does not confirm the page is complete or right for your situation.
General education — varies by person. Answers genuinely differ between people. This page explains what commonly varies and points you to your care team for your situation.
Human medical review: not completed. Pages here are not signed off by a clinician before they publish. That is not an oversight we are quietly working around: we restate published guidance and cite it, so the authority belongs to the source rather than to us, and every page names where its claims come from — you can verify us instead of trusting us. Where a volunteer clinician has reviewed a page, their name and credentials appear on it; where no name appears, no clinician has checked it. We are glad to have reviewers and are recruiting them, and we do not hold pages back waiting for one. Use this site to understand your situation and to ask better questions of the people treating you.
