Description

A protein made by the prostate that is normally found in the semen and blood. Higher amounts of PSA may be found in the blood of men who have prostate cancer, benign prostatic hyperplasia (BPH) or inflammation of the prostate.

PSA can be used as a tumour marker. It is used to monitor a man’s response to treatment for prostate cancer, or to see if prostate cancer has come back (recurred) after treatment.
