Colorectal cancer starts in the colon or the rectum. These cancers can also be called colon cancer or rectal cancer, depending on where they start. Colon cancer and rectal cancer are often grouped together because they have many features in common.

Several screening tests can be used to find polyps or colorectal cancer. It is important to know that if your test result is positive or abnormal on some screening tests (stool tests, flexible sigmoidoscopy, and CT colonography), a colonoscopy test is needed to complete the screening process. Talk to your doctor about which test is right for you.

When to Get Screened for Colorectal Cancer

  • If you are aged 45 to 75 years old, you should get screened for colorectal cancer. If you are older than 75 ask your doctor if you should be screened.
  • The U.S. Preventive Services Task Force recommends screening beginning at age 45.
  • The vast majority of new cases of colorectal cancer (about 90%) occur in people who are 50 or older.
  • If you think you may be at increased risk for colorectal cancer, learn your family health history and ask your doctor if you should begin screening before age 45.
