How does a Prostate-Specific Antigen (PSA) Test Work?

Prostate-specific antigen (PSA) is a protein produced by the prostate gland, which is part of the male reproductive system. Doctors use PSA testing to evaluate the risk of prostate cancer. Elevated PSA doesn’t definitively indicate cancer, but it’s an essential marker for assessment. Regular check-ups and discussions with your healthcare provider are crucial for older (50+) individuals with a prostate.
