Colorectal Cancer Screening
Screenings Save Lives
Colorectal cancer almost always develops from abnormal growths called precancerous polyps in the colon or rectum. Screening tests are used to find precancerous polyps, so they can be removed before they turn into cancer. The screening tests are also used to find colorectal cancer early when treatment works best.
Screening for colorectal cancer should begin after turning 50. The screening tests will continue at regular intervals after that. Some people need to be tested earlier or more often if you or a close family member have had colorectal polyps or colorectal cancer, if you have IBD (inflammatory bowel disease), or have a genetic syndromes lie hereditary non-polyposis or familial adenomatous polyposis (FAP). Your doctor can tell you when you should begin the screening process and how often you should be tested.
Colorectal cancer screening tests are used to look for the disease when there are no symptoms. Screening tests can find things that should not be there, such as colon or rectal polyps, and remove them before they have a chance to into cancer. Removing polyps prevents colorectal cancer from developing. Early detection of the disease can lead to more effective treatment. A screening test differs from a diagnostic test because diagnostic tests are used to find the cause of symptoms.
