Im 9.5 yrs since my prostecomy. My current PCP was unaware I had a prostecomy. The PSA readings were always in the 1.x range. When it rose I told my PCP that I had the prostectomy in 2012. The 2 different body scans on me showed only a small tumor. It was beneign. I’m told radiation is needed as I am at high risk to deveope cancer somewhere. At 74 Im not sure I should do the radiation since there isnt a location cause found. The PSA is at 4.1 up from 3.4 in February. Im just looking for info on side affects and cancer risks radiation may cause
