If you discover a precancerous polyp, and it gets removed during the colonoscopy, you just might avoid ever getting colon cancer instead of dying from it prematurely. But you do you.
You don't seem to even understand or care how much I would personally appreciate and welcome "dying prematurely" of any cause. This is so personal. HN such insensitive claudes here.
So if it means so much to you that I screen for colon cancer, then you can pay for it, you can drink the nasty shit, and you can shove it up your own ass, with all due respect, mister.
