My biopsy was quite similar to yours. In my case after exhaustive research and talking to a number of Doctors, I chose radiation. I was 74 at the time and ultimately felt that since the results of each procedure were almost identical in treating the cancer that avoiding unnecessary surgery was the best choice for me. Side effects exist with both approaches and are an inconvenience to be sure, but are ultimately manageable and just become part of your live-how bad they are and how much they bother you is a personal issue. Wish you the best and know you have lots of company in this fight.
