Hello, we live in the bush of Alaska. My father is a bladder cancer survivor with a urostomy. Recently he has presented with crimson blood in the toilet on and off for three weeks straight. He has complained of lower back pain and now sever abdominal cramping. He refuses to go to the clinic hear and I am concerned for him. is there a diagnosis that matches these symptoms that I can use to encourage him to go. I think it is more sever than he is willing to admit.
