Great news Steve, I bet you are thrilled to bits.
My story is almost the same as your except I went to docs in sept 2014 and my psa was 63. Had blood test on11th may and was down to 0.5 and I know how I felt with that. I have still to go for RT after a TURP op on 15th June.
Hope the heart copes with the extra thrill of your news
Cheers Chris/woody
