....myself, I wouldn't mess around with it....I started getting PSA test a number of years ago, I had a cousin diagnosed back in 92'.....I started probably ten years or so ago. As you can see I peaked with a 5 back then, mine too settled back down for a few years. My urologist told me then, it wasn't if but when I ended up with PCa..this past Feb we were finally successful in our hunting....I almost missed this past year too. He told me if I would have waited that full year, I would have been in trouble.....no doubt I had it back then. No symptoms...ever, normal DRE's...except the last one......just a small bump, he could barely feel. My surgeon agreed on the DRE, could barely feel it.....but, it all worked out, I'm thankful we found it when we did. the advances in treatment the last few years, the skill of so many Dr's in many types of treatment.....and this site is invaulable....I'd be looking for a biopsy...but then that's just me........ they can put you out for it if you wish, not all the way, but in a twilight state........good luck brother.
