Hi Stewart, i too have had RT and am still on HT until Feb next year, with the oncologist suggesting that I will be on it for longer as the new thinking is to stay on HT as long as possible.
I can see where you are coming from about no knowing but I was told at the very beginning that HT and RT would " hopefully " get rid of the PCa but Zapping it and getting the PSA down is the main target. Supposedly after finishing HT it gradually fades in your body for as long as you were on it (according to some on this site) and then there is a chance that if there is the slightest, smallest cell left it starts to increase in size as there is nothing to stop it feeding off the testosterone that should be starting to produce naturally in your body. This is when the PSA will start to rise and put you back where you started but you will not be able to have RT again.
Like you my PSA went down to .000001 and is officially undetectable but I am under no illusions as to not being "cured" and will be waiting to see what happens. I will deal with it as and when it occurs(if it does). There are dozens of other things that could take me before then.
My advice to you is stay positive and see what happens, live your life as normal and cherish the fact that you are alive and able to do what you want to, there are so many people that cannot that.
Best wishes for the future, Chris/Woody
