Hi, Lee.
I'm sorry, that you've found yourself in the club no-one wants to join, but welcome to the forum, mate.
There are plenty on here that have a similar diagnosis to yours, and there have been plenty of conversations on T3a/T3b disease with possible lymph node/seminal vesicle involvement. I will try and find some, and add links to them.
I hope your bone scan results are favourable.
There are also plenty of guys on here who've dealt with capsular breach and Gleason 9 (4+5). I'm one of them.
You are right, this disease also affects your loved ones. I often think its more difficult for them to deal with than the person with it.
Although, I'm not the greatest fan of Jeremy Clarkson. I'm glad that his story led to you getting tested. The earlier you deal with the disease the better the outcome.
Please keep us updated and good luck, mate.👍
