There are a variety of options for radiation which the radiation oncologist will explain to you. Depending where you live and or your ability to travel, this may limit your choices. The larger medical centers such as Mayo have the newer and more advanced proton machines that can treat him in 5-6 treatments over a 2 week period. Regarding your questions on burns if this happens, from what I see on this forum they tend to be minor and not a serious issue. My thought you should always get a second or third opinion. Considering your husband’s age, Gleason score and PSA, I would not be surprised if another urologist would recommend active surveillance. If travel is an issue, I did several virtual visits with urologists and oncologists.
