@jaygk I was offered 5 sessions of proton, and took it. I looked at a lot of radiation treatment modalities. The five were in two weeks. An M-W-F. then three days off followed by a Tuesday Thursday finish up. Saw the Radiation oncologist on Tuesday and they reviewed my urinary impact issues. One thing I did not do was access the Prostox test for sbrt radiation. I am not certain it would have applied to the proton format?

I had gotten complacent with what I viewed as steady state cancer while on active surveillance and had not kept up with advances in treatments the way I should have. Then the PC ramped up rapidly and I had to make decisions quickly, while undergoing back surgery. Where I live providers offer the photon sbrt 5 treatments spread over 5 weeks and I think that would have been a better fit for me.

Some people think the proton is the Magic Pill. I think both proton and photon are about equal in curative abilities. The Meridian MRI real time guided sbrt sounds good? But few facilities have that and for sure you want to go where the providers have great experience.

One other thought. Some people seem to think that if radiation is delivered On Target perfectly, then there will be no side effects. I can tell you from my experience that my prostate yelled just as loudly as my bladder did when radiated.
