Grace H. Elta, M.D., discusses the importance of colonoscopy.
DefinitionA colonoscopy is a test that allows your doctor to look at the inner lining of your large intestine (rectum and colon). A thin, flexible tube called a colonoscope is used to look at the colon. A colonoscopy helps find ulcers, polyps, tumors, and areas of inflammation or bleeding. During a colonoscopy, tissue samples can be collected (biopsy) and abnormal growths can be taken out. Colonoscopy can also be used as a screening test to check for cancer or precancerous growths in the colon or rectum (polyps).
