No. I never had any euphoria after my treatments.  Just worry each time there's a scan or blood test. 

I was 56 when I had surgery for prostate cancer.  That was just over 9 years ago and I'm still here.  Last summer I had a small operation for bladder cancer!  I tell my friends that I enjoyed the prostate so much that I thought I'd give the bladder a try ;-)

I gave up working when I reached 60 and I'm now retired and playing my mandolin in several bands. Best decision I ever made.
