I didn't really have a choice as to the type of radiation (or I should say I didn't ASK for a choice). My urologist recommended a Dr. that runs the radiation dept. at Memorial Hermann hosp. here in Houston where I did mine. My urologist is also in the same hosp. system. I must say I was putting all my confidence in my urologist as to my best course of treatment so I hope I made the right choice. I finished the 2nd of July with 39 treatments and so far so good. You are lucky you will not need ADT as that stuff is rough on some people. Good luck with your journey and remember all treatments will have some side effects, I looked at my history with drugs I have taken over the yrs and I have had none to very few side effects so hopefully this will be the case with my radiation.
