Hello, Had a prostatectomy in 2006 at age 53. Gleason score was 6. PSA pre-surgery never higher than 1.1. Pathologic stage: pT3a N0 MX R0. Tumor had breeched capsule on one side but margins were clean as were lymph nodes. Have had PSA tested annually since then and it always came in at 0.01. However, just had my annual PSA yesterday and the number has increased slightly to 0.04 at age 69. Should I be concerned? Or just continue checking it annually and reach out to my urologist if/when it exceeds .2 or .4? Thanks.
