I had a radical prostatectomy in 2001. My pre-surgery PSA was 11, my Gleason score was 7-8, and there was cancer in the seminal vesicles, but none in the margins or lymph nodes. I've had no post-op treatment of any kind. My post-op PSA went to less than .04, but has gradually crept up over the 13 years since my surgery and is now .31. The increase has been roughly linear. I was at .15 in 2008, and experienced a .03 decrease in 2011. I am not one to pursue aggressive measures to stomp out a condition that may or may not be indicative of a recurrence. And in fact, in a discussion with my urologist two years ago, I was told that based on the very slow progression of my PSA, I may just be harboring some residual condition that's not going anywhere, and that he could see no reason for further treatment unless I were to experience a sudden and significant PSA spike. I am 71 years old, in excellent physical condition, and have no other health issues. What would you recommend?
