1. A Colonoscopy Has Many Benefits

A colonoscopy can diagnose and prevent colorectal cancer. Colorectal cancer is the second leading cause of cancer-related deaths in adults in the United States, according to the American Cancer Society. Colonoscopy can detect early-stage colorectal cancer, when it is easiest to treat. Doctors can also use it to remove colon polyps. Colon polyps are growths that can develop into cancer. Colonoscopy is also accurate, minimally invasive, and covered by most insurance plans.
