With your score of 3+4 , which is what my biopsy showed you have a lot of options. One of the radiation oncologist I consulted told me the difficulty is choosing the one that is best for you. Surgery and the various types of radiation all have documented good results. They all have pros and cons. Do not hesitate to get several consults with urologists and radiation oncologists before you make your decision. I did some virtual visits with various specialists including Mayo and found this to be helpful. Then decide what fits your lifestyle and what you are comfortable with.
