I've been dealing with this since 2008 when I had radical prostatectomy and was clear for 11 years when it reappeared. I then had hormone therapy and 36 radiation treatments. Sine that time it has been slowly rearing it's ugly head. Four PET scans later, there is still nothing to see yet. It may happen and it may not happen to find it. At 80 years of age, I will still seek treatment when I know where and what might work. Still as physically fit as I was 20 years ago for the most part.
