What is colorectal cancer?

Colorectal cancer is a cancer that develops in the colon or the rectum. These cancers are sometimes referred to separately as colon cancer or rectal cancer, depending on where they start. Colorectal cancer is the second leading cancer killer in the United States, but it doesn't have to be. If everybody aged 50 or older had regular screening tests, most of the deaths from colorectal cancer could be prevented.

Is there something I can do to help prevent colorectal cancer?

Yes! Colorectal cancer almost always develops from precancerous polyps (abnormal growths) in the colon or rectum. Screening tests can find precancerous polyps, so that they can be removed before they turn into cancer. Screening tests can also find colorectal cancer early, when treatment works best.

  • You are 50 years or older
