Glossary Term:


colorectal cancer screening




testing done to find abnormalities early, before signs and symptoms start. This allows cancer to be found earlier, when it is most curable. Some types of screening allow doctors to find and remove polyps, which can even prevent cancer from developing. See also screening, barium enema, colonoscopy, fecal occult blood test, fecal immunochemical test, polyp, sigmoidoscopy.
