A colonoscopy is a colon cancer screening and prevention test. 90% of colon cancer comes from polyps. A colonoscopy can allow the detection and removal of pre-cancerous lesions (polyps) and allow removal. A single colonoscopy can decrease the risk of colorectal cancer by 70%.

A colonoscopy is performed for colorectal cancer screening starting at the age of 50. It is a routine preventative test for the identification and removal of polyps, some of which may become cancerous if not removed. Colorectal cancer occurs in 5-6% of the population and is the second leading cause of cancer-related deaths in the U.S.
