I had prostate cancer and had a radical prostatectomy Feb 2009. Gleason 3+4, PSA 4.2 preop, 0 of 18 nodes positive, largest tumor 1.5 x 1.1 x 1.0. right margin very close but no residual tumor- Stage T2c No. brother died of prostate cancer Gleason 4 + 4. Psa on April 2009 zero and remained essentially zero at 3 month intervals (except occasional 0.01) until June 2013. Psa Sept 2013= 0.03, psa Jan 2014 0.03, psa May 2014 0.04, and psa August 2014= 0.05. The question is " should I be concerned with this elevation and if not, then at what point should I be concerned about recurrence and then what workup should be pursued and what treatment should be considered. Thank you.
