Prostate-specific antigen (PSA) test

Prostate-specific antigen (PSA) is something made by the prostate gland. High PSA levels may be a sign of prostate cancer, a noncancerous condition such as prostatitis, or an enlarged prostate gland. This is a test that screens for prostate cancer, it  measures the amount of prostate-specific antigen (PSA) in your blood

High PSA levels could be a sign of prostate cancer or a different condition like prostatitis or an enlarged prostate.

Other things can affect your PSA level:

• Age. Your PSA will normally go up slowly as you get older, even if you have no prostate problems.
• Medications. Some drugs may affect blood PSA levels. Tell your doctor if you’re taking dutasteride (Avodart) or finasteride (Propecia or Proscar). These drugs may falsely lower PSA levels by half of what they should be.
