Hey there, sorry to hear of your diagnosis. That is a shock. You have had aggressive treatment, and may do very well indeed. Never give up hope!
Unfortunately (or maybe fortunately), there are not many cases like ours. High grade PCa, "very high risk" with G9 and multiple positive cores, stage 3, all add up to a challenging case without a lot of guidance for the doctors. These are pretty rogue cells, and it's a bit hard to predict the course of such a case.
I started a thread some years ago for what I called the G9 Crew, so you may find a number of people who've been here and what their situation was. As you're finding, the support just due to numbers tends to be around guys dealing with pee dribbles and weak erections. The G9 folks are usually less concerned about
that, and looking for ways to
survive. It's a different focus, and you won't find a lot of understanding among the G6 and G7 cases. It's just the way it is.
Here's a link to the latest version I know of for the G9 Crew thread. You may find it interesting. There are links to the threads for many of them. All the best as you move forward; it sounds like you're in good hands now.
