Sorry to hear about the .2....when mine hit .24 post-surg, my Uro summed it up best "that sucks..." And yes, its very upsetting.
But....it took you 8 months to get there, that's not all bad. PSA doubling at these low levels might not mean too much, plus you had a positive margin. That actually increases you chances there is just residual disease in the prostate bed...and will be cured with radiation.
Salvage radiation isn't all that bad. I had mine done at a local rad. oncologist --- I looked into photon and world class centers, but really didn't see too much advantage. I had 36 sessions, and it only took 10 minutes to get there each day.
The main thing I'd ask about is if the docs recommend doing hormone therapy in addition to the radiation...and if so, how long? I did 2 zoladex shots, three months apart. THe effects of HT lasted about a year....my results are in my signature.
I was your age when I had this going on....it really sucks to be dealing with this so young, but the up side is you can tolerate the treatment a lot better.
This is a curable condition, and by acting this early, you really increase your odds of a durable response. You seem to be willing to throw everything you can at this thing --- keep it up---you're going to win!
