A colonoscopy is a procedure that helps detect and prevent colon cancer. Experts recommend colon cancer screening for all adults starting at age 45, with repeat screenings at least every 10 years. People who have a higher risk of developing colon cancer should get a colonoscopy earlier and more often. This includes people with a family or personal history of colon cancer and those with certain forms of inflammatory bowel disease (IBD).
