Daddys lost another 17 pds in about two months. Hes lost over 60 pds in a year and a half. All bones. Doctor says he cannot see what is going on without a colonoscopy but that he may have colon cancer. He has alot of the symptons and always has stomach pain. Diarreah, constipation. But were not going through a colonoscopy because we would not do the treatments. I read you could live 5 years. Any insight?
