Hi Sandy,
If you want cheering up, check out my profile, we have a lot of similarities:
I was diagnosed when I was 54 with Gleason 9.
RT & HT were the only treatment options. Incidentally you need a total of 3 years HT along with the RT. Initially this is to shrink the tumour so they can focus the RT beams on a smaller target. Then you need it afterwards to stop the cancer cells growing while they die. (Look up 'adjuvant hormone therapy' on Google.)
My consultants told me, because I asked them outright, direct questions, that firstly with Gleason 9 I was likely to die of PCa, and that the RT had at best a 60% chance of curing me. Incidentally they define a cure as keeping me alive long enough that I die of something else.
In the event it didn't cure me, but I have subsequently had salvage HDR Brachytherapy, so even if your cancer comes back you should be a candidate for that treatment, and while I am not counting my chickens that too has knocked the cancer back, maybe a cure, more likely an extra few years remission.
My last PSA test was 0.2 so I should live to see the swallows return this summer and I will then have survived 10 years post diagnosis.
So plenty of reasons to be cheerful.
:)
