Hello, I have had UC for 31 years. I'm monitored closely by GI these days and feel as though they are doing everything they can for me. If flares are kept in check that's the big thing, the more inflammation the higher the risk is what I've read. Diet for me has been key. No coffee at all. Dropping coffee out of my diet stopped the need to run and I do mean run to the bathroom. I had no idea. I'm sure everyone is different, but that was key for me. I also don't eat raw veggies, too hard to digest. I do enjoy cooked veggies and try to get them into my diet regularly. Best Wishes
