If you were scoped 6 months ago, your chances of having rectal/ colon cancer is nil to none. A polyp generally take 10 yrs to turn cancerous. Keep a food journal and see if there is a connection between foods and how it might effect you. Example for me, I love my greens, butt those greens especially spinach will give me the runs.
Try not to worry,
