No, but a Colonoscopy is the only procedure that allows both identification and removal of polyps, thus preventing colon cancer. A screening colonoscopy is also covered by most health insurance plans at 100% after age 50. A Cologuard stool test is another option for screening, but it is meant to detect cancer, not polyps; it requires that you submit a stool sample to a laboratory. CT Colonography is another option for screening in which a bowel prep is required and radiation via computed tomography is used. If either Cologuard or CT Colonography are positive, then you will require a Colonoscopy to evaluate the colon and remove polyps. Please keep in mind that if any alternative screening test is used and is positive, the subsequent Colonoscopy will be diagnostic, not screening, and therefore, no longer covered at 100% by your insurance plan.
