What are prostate-specific antigen (PSA) levels for prostate cancer?

ANSWER

Prostate-specific antigen (PSA) is a substance produced by the prostate gland. It is normal to secrete small amounts of PSA into the bloodstream. Larger amounts of PSA in the bloodstream usually signal that the prostate gland is enlarged, infected, or malignant. PSA levels are determined by a simple blood test. The higher the number, the more likely the patient is to have prostate cancer.
