Colon Cancer

My sister's husband had colon cancer surgery and it was a surprise. He had a colonoscopy 4 years ago and was told he didn't have to have another for 10 years. I guess when you get over 80, you need to have a colonoscopy more often than some doctors suggest. They were able to get all the cancer and he doesn't need further treatment. That is sure a good thing. Chemo makes everyone so sick, they wish they were dead anyway.
