Normal caveat of "I'm no doc, or expert, just been down this road" From what I've read, you can increase your PSA that much by being slightly dehydrated, riding a bicycle or having sex. I think you would need one more PSA test at least to establish any sort of trend at all.

Not sure when your next chat with the Doc is, but, my guess would be another blood test in 3 months to see if it continues up or it was an anomaly caused by something else.

A .5 increase in a year might be concerning for someone who is younger, with no history and a normal PSA down around 1 or 1.5 as that is a 33.33% increase. Yours is considerably less as a percentage.

You certainly need to keep an eye on it, and you're going to experience the unfortunate side effect of the anxiety, it's only natural, however, it's the next test or two that will likely give you your answers.

So what to do, mitigate the anxiety as much as you can by keeping busy and enjoying life! (pretty much the only thing that works for me!)

Best of luck to you!
