I am currently waiting on my first Proton radiation treatment of five at Mayo Phoenix to start on April 17. You like me have unfavorable intermediate risk prostate cancer. I did not want surgery. My PSA was 2.9 and my biopsy showed 4-3 Gleason with some 3-4 all confined to the prostate on one side at the base. I would have preferred to get the Mridian Viewray but there are no centers nearby. Nearest is in California. I would have liked to do the HIFU but the doctor who did my transperineal biopsy said I had too many calcifications to try it and did not want me to be a guinea pig. That is why I chose radiation. I am 73 and 7 months old so if the treatment gives me 15 years I am now almost 89 and wonder what life will be like at that age.
