HI, my reply may not be particularly helpful, so these are just my thoughts and experiences since undertaking my treatment journey since last February. Although I'm far older than you ( 71 ) my scores at diagnosis were similar, although I was borderline whether my problem was confined to the gland or had broken out of the capsule
I attended UCLH and saw three "specialists" all of whom had a different take on my treatment options, robotic surgery being the first one, this was however contradicted by another specialist who said urinary problems would be almost certain due the location of my tumor, I didn't pursue why three specialists came to different conclusions.
The third consultant immediately put me on a hormone deprivation drug to as he put it " stop it in it's tracks" quite why the first consultant didn't do that is a mystery and yet another question that I did not ask !
After surgery was ruled out I was then referred to have 20 weeks of radiotherapy, along with Androgen deprivation therapy, via a 3 monthly injection to suppress Testosterone production, the treatment notes I have in my possession stating the treatment goal being "curative". I have just gone for my first post treatment check up, and was told my PSA levels were now undetectable.although I'll have to stay on hormone therapy for three years ( although I'm going to question this at my next check up ), but this varies, for a friend of mine it was just 6 months, and nearly ten years on he's still fine.
So what's the point I'm making, and in some ways talking to myself as I write, but I don't think it's an exact science, otherwise why would one specialist suggest surgery, whilst at the same time on the face of it, ( and fingers crossed) a non surgical route apparently can have the same result, with non of the risks associated with surgery....... this is absolutely the question I would be asking should I be starting all over again on this journey.
At the end of the day only you can make the decisions, but as you are doing ask, and read as much as you can before opting for anything, at least you should then be making a better informed choice, it's your body, and your life, not theirs................good luck, Eric
