Colonoscopy is associated with a reduced risk of developing colon cancer by identifying and removing colon polyps that can grow over time.

The effectiveness of a colonoscopy depends on how thoroughly the bowel is cleansed before the procedure. The better the bowel preparation, the higher chance the endoscopist can identify and remove polyps, which reduces the risk of future colon cancer.
