New study on colonoscopy finds they may not be that effective at preventing colon cancer, death. But you still need regular colon cancer screening, doctors say.
It’s covered every 48 months (four years) if you are age 50 or older and at high risk, or once every 10 years after a colonoscopy if you are 50 or older and not at high risk. Stool-based tests
Some medical societies in the US recommend a screening colonoscopy every 10 years beginning at age 50 for adults without increased risk for colorectal cancer. [25] Research shows that the risk of cancer is low for 10 years if a high-quality colonoscopy does not detect cancer, so tests for this purpose are indicated every ten years. [25] [26]

[6] The distal phenotype may demonstrate numerous small polyps in the distal colon and rectum, whereas the proximal phenotype may be characterized by relatively fewer, but larger polyps in the proximal colon (cecum, ascending colon, etc.).
