That's how it works in the Scottish NHS. National stool screening program every two years after you turn 50 (you get mailed a sample tube and send it back to the test centre). If it's a positive, you're called in for a colonoscopy. *But* if you show suspicious symptoms outside of the screening program you get a colonoscopy anyway. (Source: am at very high risk of hereditary colon cancer, had a colonoscopy when my GP learned of the family history, then screening thereafter. All clear so far ...)
