Colorectal Cancer Screening

Screening Saves Lives

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.

When Should I Begin to Get Screened?

You should begin screening for colorectal cancer soon after turning 50, then continue getting screened at regular intervals. However, you may need to be tested earlier or more often than other people if—

• You or a close relative have had colorectal polyps or colorectal cancer.
• You have inflammatory bowel disease.
• You have genetic syndromes such as familial adenomatous polyposis (FAP) or hereditary non-polyposis colorectal cancer.

Speak with your doctor about when you should begin screening and how often you should be tested.

What Is Colorectal Cancer Screening?

Screening is when a test is used to look for a disease before there are any symptoms. Cancer screening tests, including those for colorectal cancer, are effective when they can detect disease early. Detecting disease early can lead to more effective treatment. In some cases, screening tests can detect abnormalities such as polyps, before they have a chance to turn into cancer. So removing polyps prevents colorectal cancer from developing.

Screening Demonstration Program

CDC has established a colorectal cancer screening demonstration program at five sites aimed at increasing colorectal cancer screening among low-income adults aged 50 and over who have little or no health insurance coverage for regular screenings.
