I was diagnosed with a PSA of 7.9 and a Gleason of 4+3=7. I contacted the Mayo Clinic in Phoenix in July of this year, had a consultation with a radiation oncologist, had a bone scan (clear), minor surgery for Space OAR and prostate markers, and just started Pencil Beam Proton Therapy last week. I’ve had 2 sessions thus far of the Proton Therapy and will have my 3rd today. A total of 28 sessions have been scheduled out for me. I did a ton of research regarding how to proceed with treating my cancer and feel, so far, that I made a good choice. The daily Proton treatments are a piece of cake. The stress of getting to the point of starting treatment, on the other hand for me was quite unnerving. So, I would encourage you to keep trying to see if you can go the Proton route. Best of luck and hang in there….
