The full explanation.

The simple version

Here's a friendly checklist of habits that are linked with lower cancer risk. You don't 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 — aim toward 150 minutes a week, building up slowly
  • Sit less and take short movement breaks
  • Work toward or keep a healthy weight, in a kind and realistic way

Eat and drink

Gentle, non-restrictive choices:

  • Eat more vegetables, fruits, whole grains, and beans
  • Limit processed meat and red meat
  • Limit or avoid alcohol

Protect and prevent

Other steps that help:

  • Don't smoke — and ask for help quitting if you do
  • Protect your skin from the sun
  • Get vaccines when appropriate, such as HPV and hepatitis B
  • Ask your doctor which screenings are right for you
  • Support your health with good sleep and stress care

A kind reminder

This checklist is about giving yourself the best chance and feeling your best — 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.
