For people at average risk for colorectal cancer, the American Cancer Society recommends starting regular screening at age 45. This can be done either with a sensitive test that looks for signs of cancer in a person’s stool (a stool-based test), or with an exam that looks at the colon and rectum (a visual exam). Talk to your health care provider about which tests might be good options for you, and to your insurance provider about your coverage. No matter which test you choose, the most important thing is to get screened.
If you’re in good health, you should continue regular screening through age 75.
For people ages 76 through 85, talk with your health care provider about whether continuing to get screened is right for you. When deciding, take into account your own preferences, overall health, and past screening history.
People over 85 should no longer get colorectal cancer screening.
If you choose to be screened with a test other than colonoscopy, any abnormal test result needs to be followed up with a colonoscopy.
