I am already done with the SRBT 5 dose Proton treatment at Mayo Phoenix. It has been 35 days since my last dose and the side effects have been minimal to the point I wonder if they even gave me radiation. I had slight pinkish discharge before a bowel movement the first two weeks after (more like a wet pinkish fart) and two 5-inch pink circles on each hip where the beams were aimed. I almost felt guilty ringing the bell. Only time will tell if I made the right decision. I did get the SpaceOar gel inserted to protect my rectum and hopefully have no problems in the future. Urine flow is fine, and I still drink my two mugs of coffee every day so no bladder irritation.
