Colorectal cancer prevention

Prevention and early detection are different, complementary discussions. Healthy habits help reduce risk; screening looks for changes in people without symptoms, according to clinical criteria.

Are prevention and screening the same?

No. Prevention includes measures to reduce risk. Screening uses tests in people without symptoms to look for early changes. Symptoms require diagnostic assessment independently of a screening schedule.

When should I discuss screening?

Age, personal and family history and previous tests help determine when to start and which methods to consider. Ask for individual advice; general guidance does not replace your own risk assessment.

Does family history change the assessment?

Family colorectal cancer or polyps may influence recommendations. Note which relatives were affected and, if known, their age at diagnosis. The team can assess whether genetic risk investigation is appropriate.

Which habits matter?

Diet, physical activity, body weight, smoking and alcohol use are part of prevention discussions. Preventive measures reduce risk but cannot guarantee that a person will never develop cancer.

I have had polyps. What is the next step?

Bring previous colonoscopy and pathology reports. Follow-up after polyps depends on findings and history; a single interval is not appropriate for everyone.
