PSA is a secretion of prostate epithelium and is also produced by prostate cancer cells. It is a glycoprotein with protease activity. It can be used with digital rectal examination (DRE), and ultrasonography to detect prostate cancer. PSA may be elevated in prostate cancer or BPH (benign prostate hypertrophy), prostates, urinary retention, urethral instrumentation, needle biopsy, etc. Elevated PSA can only suggest the presence of prostate cancer.
