shep247: my treatment experience was based on my research (including this web site) and my discussions with my doctors. After the urologist and discussions with 5 highly trained and experienced radiation oncologists, I narrowed my decision down to Proton or the Mridian narrow margin radiation machine. I chose the Mridian and would do it again if I had a biological reoccurrence. How much your healthy tissue is exposed impacts side effects. Many success stories on this web side with different choices but my 2 mm margins vs 3-5 mm with proton and other types of photon radiaton machines makes a difference and is worth asking for specifics from your radiation oncologists, including the built in MRI so the Dr can treat in real time not fused images. Quality of life was a big focus for me. I did not have Androgen therapy. My side effects were minimal with a little restriction with my urine. No pain or bleeding. I also had spaceoar inserted to separate the rectum from the prostate for less exposure.
There is a lot to absorb but keep coming back and ask questions and you WILL start to zero in on what you feel most comfortable with.
