The harm can be from the initial screening too. The lifetime risk for complications from routine colonoscopy is around 1.6%. The lifetime risk of colo-rectal cancer is 4-5%.
So already before investigating the result, there's a very real consideration whether increasing the number of colonoscopies is likely to be a net benefit.
