The primary purpose of a colonoscopy is not to diagnose colon cancer but rather to find and remove any polyps before they become cancerous. In this way, a colonoscopy is primarily performed to prevent colon or colorectal cancer. At the same time, a colonoscopy is still a highly accurate way of detecting colon cancer. With that in mind, your doctor may determine that you require a colonoscopy for any of the following reasons:

– If you are at least 45 years of age, your doctor will likely recommend a colonoscopy to screen for colon cancer, which is repeated every ten years unless polyps are found, in which case subsequent screening will take place sooner.

– If you are experiencing signs and symptoms of intestinal issues, such as abdominal pain, chronic constipation or diarrhea, rectal bleeding, and other problems.

– If polyps have been detected, your doctor may recommend a colonoscopy to remove them or to look for more.
