My first reaction was to have surgery. After doing more research, including doing a lot of reading on this site, I changed my mind and went with a BT/IGRT combo. Primary reasons were I did not want to go through major surgery at my age and wanted to minimize side effects if possible. All indications were that BT/IGRT would accomplish that with equal cure rates vs surgery. I have been very happy with my decision. The minor SE's I experienced have all but disappeared.
That said, you will find guys here that had surgery and are satisfied with their results as well. You are a candidate for both. Take your time, learn as much as you can, consult with your family and then do what feels most comfortable to you. Best wishes on the journey.
