Men over the age of 40 should get a baseline PSA test. After that, every 5 years until they turn 50 and every year after that.
At your family doctor or at the Man Van™.
Elevated PSA levels can be a result of many things unrelated to cancer, including:
-Enlargement of the prostate
-Prostatitis (infection of the prostate)
-Recent prostate procedure (i.e. biopsy)
