There are more options becoming available. I think most people think of surgery to just get the cancer out of their body. Sometimes that works but sometimes it does not. I guess to be honest there is no 100 percent certain way. I think there are 3 aspects to treatment; financial, emotional, and physical. The individual needs to deal with all three of these and then after much research make a decision as to what treatment he will take.
There are many here and vertually every option was choosen by someone who will be glad to respond to any questions you might have.
My final choice was proton but I am getting a 3 fer. Hormone therapy to starve the sucker, Photon Conventional radiation to try and target any cancer outside the prostate, and finally 17 dose of Proton to the prostate and a suspect lymph node. We, my wife and I, feel very comfortable that we made the right choice and look forward to completing treatment and getting on with watching our 12 grand kids and soon to be first great grand child grow to adulthood.
You have come to a great place for support and information.
You could not ask for a greater group of people who are going down the same path as you and dealing with it each and every day.
The best to you and yours
