Progressive screening using non-invasive assays like Cologuard and FIT is a valuable screening mode. The non-invasive assays are not perfect but they are improving.

You have to weigh the risk of complications from the colonoscopy (primarily bowel perforation) with the improved outcomes. There's a cost element as well, since colonoscopies (without complications) can be several thousand dollars.
