Colonoscopy is a test that allows one of our board-certified gastroenterologists to exam the inner lining of your large intestine. While you are sedated and comfortable, he or she uses a thin, flexible tube, called a colonoscope, to look at the colon.

A colonoscopy is useful in finding colon growths (polyps), tumors, sources of bleeding and areas of inflammation. During a colonoscopy, tissue samples can be collected (biopsy) and abnormal growths can be removed.

Colonoscopy is also frequently used as a screening test to check for colon cancer and to remove precancerous growths in the colon. Screening is usually recommended starting at age 50. If you have a family history of colorectal cancer or colon polyps, even earlier screening may be recommended.
