A screening test is used to look for a disease when a person doesn’t have symptoms. (When a person has symptoms, diagnostic tests are used to find out the cause of the symptoms.)
Colorectal cancer almost always develops from precancerous polyps (abnormal growths) in the colon or rectum. Screening tests can find precancerous polyps, so that they can be removed before they turn into cancer. Screening tests can also find colorectal cancer early, when treatment works best.
Regular screening, beginning at age 50, is the key to preventing colorectal cancer. The U.S. Preventive Services Task Force (USPSTF) recommends that adults age 50 to 75 be screened for colorectal cancer, and that adults age 76 to 85 ask their doctor if they should be screened.
Most insurances cover colonoscopy at 100%. A colonoscopy must be scheduled through the Johnson Memorial Surgical Specialists office. The procedure is provided at as an outpatient at our Surgery Center.
