Flexible Sigmoidoscopy
Flexible Sigmoidoscopy checks for polyps in the lower bowel, including your rectum, sigmoid colon, and your descending colon. This test must be performed every 10 years. A thin, flexible, lighted tube (sigmoidoscope) with a tiny camera at its tip is inserted into your rectum and then travels about 2 feet through your colon. If polyps are found, a colonoscopy is required.
