I think you have had your meeting with the oncologist by now, so an answer to your "questions" is probably too late, at least for now. However, I am wondering who told you the cancer was aggressive in nature. A Gleason of 6 is not a sign of an aggressive cancer. Most all of us would be happy with a Gleason of 6. If you had an 8, 9 or 10 then you would have an aggressive cancer. I'm interested in finding out what the oncologist suggested. Bob
