Here in the U.S., most doctors recommend the PSA ( prostate specific antigen ) test at each years general physical exam, but what I've found is that the PSA test can show elevated results (normal 2.0 - 4.0 nanograms per millimeter of blood)) very quickly and just as quickly return to normal... say within 3 to 6 weeks. My doc says this is due to various things, such as bladder infection, prostatitis, age, etc.
I found that there's another test than can help confirm or decide what the PSA test is telling one. It's known (at least in the U.S.) as the "percent-free" PSA. One authoritative site says: " Typically, men have a percent-free PSA above 25%. Between 10% and 25% is considered an intermediate range and below 10% is considered to be low." Rendered differently, the per-cent free test should be above 25%. Even then, a good Urologist may strongly suggest a biopsy (this is not a thing to be considered lightly and you may wish to request an anathesia).
As the poster has stated, the important thing is to get the test...
