Greetings, Oncas. I believe every person here made the choice that they thought was right for them. Of course, they had lots of input - not the least of which was from medical professionals. My urologist is not a surgeon. He does general urology with a specific specialty of impotence issues. Thus, he told me that whatever option I chose I would have to see someone else. He had a recommendation, but he made sure that I was aware of all the options. He gave me a book to read before making a decision or consulting with anyone else. In the end, we chose surgery because it seemed that at my age that option gave the best options for long term survival and also if the cancer came back I still had other options.
By the way, when I had my presurgery consult and tests at the hospital, the nurse got a little worried. Here I was a 55 year old guy and had never been put to sleep, never had a broken bone, never even had a stitch from a cut. She got the anestheology guy on the line just to make sure I didn't need to do anything special to prepare. In the end it all went well.
In the end, you and your loved ones need to make the decision that is right for you. I'll be the first to admit that because of the success of my surgery, we are somewhat prejudiced toward that option. However, I recognize that the other options are right for some people. My Dad was diagnosed in his early 70s and had radiation. At 81 his PSA continues to be low and he is doing fine.
There are lots of options - make the decision that is right for you and don't look back. You have lots of support here and hopefully at home as well. Best wishes as you make this decision and move forward with your healing and recovery. David
