Colonoscopy IconColonoscopy is done to view the rectum and colon, using a colonoscope, which is a long, flexible tube with a camera on the end. Colonoscopy is done to check for colon cancer and other problems in the intestines, as well as to treat and remove polyps. A biopsy can be done during a colonoscopy to look for microscopic evidence of disease. 

AGA also offers a Colorectal Cancer Clinical Service Line to support high-quality patient care.
