here is my story,
i too ,after 4 years since my brachy ,noticed each psa test ,it was going up.
after a third 3 month test of psa rising, i informed my oncologist. it was still under 2 and under nadir, but i am a believer of ""why wait for spring, do it now" type of person.
did 3 scans. one for soft tissue, second for bones and last scan, actually on the prostate.
seems there is a spot ( my term) and she said a focus treatment of brachy should do the trick to finally eliminate any recurrence. jokingly said my wife will enjoy me for another 30 years. ( i am 77)
awaiting phone call to prepare myself for the brachy "focus".
time will tell of course how it works out.
so, it is possible. remember your still have a working prostate and i read somewhere, 40% have recurrence. the trick is to get at it asap, i suppose.
Interesting story and thank you......I didn't know that they could do BT again?
