Dow,
We all know how you feel right now, "numb" is a good word to describe it.
The tests your uro is going to ask for are probably CT scan and Bone scan, we all go through that to see if mets show up and to establish a baseline.
There are lots of G9 guys here doing find, so don't panic.
I was a G3+4+7, 10-12 core. I did surgery and will use radiation as a follow up if cancer reappears. You may also need a couple of treatments to beat this beast also.
As my uro said, from now on your life is going to change.
We are all here to help you, you are not alone.
Bill from Florida
