That was the argument my wife was giving me six years ago. The stool tests she took showed nothing. She died two weeks ago after a grueling battle with rectal cancer. You're not going to convince me.

Just to add to this comment, this is specifically in population level studies rather than on a per-individual basis.

Until otherwise proven, I'm not convinced that's not just insurance company propaganda, with the goal of not covering colonoscopies for younger people.
