Recurrence treatment does not go on the standard PSA numbers. According to the PCF anything over .2 you should be seeing a Urologist as soon as possible. Personally I started out at .1, went to 1, then 1.31 and finally 1.6. Your Gleason score will tell the Radiation Oncologist just how aggressive your recurrent prostate cancer is. I had 39 external beam radiation treatments and a 6 month shot of Lupron. God Bless and good luck
