I was diagnosed with prostrate cancer end of July 2015. In October, I had a radical prostatectomy at the VA hospital. In January, I had a follow-up PSA test with a level of 0.07. The doctors told me it should be 0.00 but no more than 0.02 so I still have cancer somewhere in the tissue. My Gleason index was 4+4 after the surgery. I will start the radiation treatments in mid-April. They said I had an aggressive cancer on my prostrate. I am wondering if my PSA is high enough to warrant radiation treatments?
