What to Expect From a Colonoscopy | Healthmad
A colonoscopy is a screening test for colon cancer. It is uncomfortable but doctors recommend you have your first screening at age 50 and thereafter every ten years, unless you have a family history of colon cancer, if so, you will need to be tested earlier and every five years. New testing that is less invasive is being done on certain individuals. Ask your doctor if it would be better for you. It requires no sedation and you avoid much of the discomfort of a regular colonoscopy.
