Hi. I'm 51/M, Generally Healthy. I'm Concerned About My Prostate.

Hi. I'm 51/M, generally healthy. I'm concerned about my prostate. A few weeks ago I was turned down for a new life insurance policy due to "elevated PSA." It was a surprise but I started paying attention to my urination and noticed that sometimes lately after I think I'm finished and pull my pants up a little more leaks out. I also have a history of sometimes masturbating hot several hours at a time after which I can feel the prostate swell and my urine stream is narrowed. Generally my stream is normal, I never wet the bed, no abnormal urine. I scheduled an appointment with my GP for next week but can't stop worrying about prostate cancer (no family history except one cousin). Your thoughts? Thank you,
Gilbert
