radiation and colon damage

I was diagnosed with prostate cancer in January 08. I had 40 radiation treatments in Feb. and March of 08. Before the treatments were over, I was bleeding from the rectum. My doctor said not to worry. But I have gotten worse. I had surgery in April 09 to burn the bleeding points. It has not helped. I am looking for answers. But, I have not found any that are encouraging. Is there someone out there that has had this experience. Can you tell me what and where you got some help?
