Acording to my Doctors the longer you have UC and once you go over ten years with it your chances of developing colon cancer increases allot, and depending on you family history it could be a substantial increase! For me I was first diagnosed in 1990 and I have a history of colon cancer on both sides of my family, with my mother dieing from it at age 62. When I went to Mayos a few years ago the gastorenterologist told me with my UC and my history that I should have a colonoscopy every 6 months, I had been getting them every 2 years, when I got back to my home and talked my own gastroenterologist about
it, and he agreed with the Mayo report, but also felt that yearly would be sufficient, and my insurance went along with that. So I get a full colonoscopy annually. Every time I have one they remove 3 or 4 precancerous ademonas, and as long as they get them early I don't have to worry about
them developing into colon cancer. So far I have been lucky and not have had a major flare in quite a few years I do get small ones every once in a while but even those are getting less frequent!
