The American Cancer Society recommends that people at average risk of colorectal cancer start regular screening at age 45. This can be done by direct visualization with a screening colonoscopy. People who are in good health and with a life expectancy of more than ten years should continue regular colorectal cancer screening through the age of 75. For people ages 76 through 85, the decision to be screened should be based on a person’s preferences, life expectancy, overall health, and prior screening history. People over 85 should no longer get colorectal cancer screening.
