If you’re age 45 to 75 years, you should get screened (tested) regularly for colorectal cancer. If you’re age 76 to 85 years, ask your doctor if you need to continue to get screened.

You may need to start getting screened before age 45 years if colorectal cancer runs in your family.

Colorectal cancer is a cancer that develops in the colon or rectum, which are parts of the large intestine. 

There are several kinds of screening tests for colorectal cancer. You can even do some at home. Before your next doctor visit, learn about the different types of tests that check for colorectal cancer. Then, use that information to talk with your doctor about which test is right for you.

You can also take this quiz to find out which screening test you might prefer.
