Hi David welcome to this site and sorry that you have to be here but we are all in the same boat as you either by being the patient or other halves or family, it touches us all.
I was diagnosed in Feb 2015 with PSA 63 Gleason 3+4=7 aggressive PCa confined to the capsule I was only offered HT and RT as my prostate is too close to the rectum wall with a risk of leaving a trace or breaching the wall, either way I did not have the choice to make.
I can only say that for me my PSA went down to 0.5 after six months on HT and following RT has dropped to 0.01 and undetectable, so am in a good place at the moment.
All the side effects of both HT and RT were tolerable although tend to get me down occasionally but my view,is it is better to be alive.
Although I have no libido (part of side effect) and have hot and cold flushes with general fatigue I am glad that I did not have to go through the ED and incontinence issues that so many others have after having a radical prostectomy. It would still have been my decision if a prostectomy had been offered.
There may be others on here that will tell you their story or experiences and once you have divulged all the information from all sources I am sure you will make the right decision for you, unfortunately only you can make it.
You can call the nurses on this site and talk to them for anything that you feel that needs explaining better, they are really knowledgable and will help you tremendously.
Best of luck with whatever treatment path you choose.
Regards Chris/Woody
