My PSA was low at 6 so my cut off point of 2 also seemed high. The comments given to me were at that level it's acknowledged you're out of remission so we talk about whether treatment starts then or wait.
As regards 'cure', to this day it's never been said to me. But I do get "you're doing exceptionally well". Better than nothing -:) I don't think they're being pessimistic just some onco's never use the word. At time of RT the onco's first words were " we're not talking cure here"
I was 0.3 after 18 months of HT ending so your level reads pretty good.
As regards energy and just feeling OK. It took about 9 months before I began feeling better then a long haul to get any kind of fitness. To this day no matter how healthy and fit I am I still get anything going. Just caught a cold for Xmas again !!! - marvellous.
Dealing with the uncertainty is difficult. Sorry no magic answers for that. I just muddle through life and deal with whatever comes when it does - that's how I was pre PCa so guess I'm back to normal in that respect
