PROSTATE SPECIFIC ANTIGEN (PSA) SCREENING
Prostate-specific antigen (PSA) test is a test that measures the level of PSA in the blood. PSA is used to screen for prostate cancer.
PSA is a substance made by the prostate that may be found in an increased amount in the blood of men who have prostate cancer.
PSA levels may also be high in men who have an infection or inflammation of the prostate or BPH (an enlarged, but noncancerous, prostate).
