The PSA test measures the level of prostate-specific antigen, or PSA, in your blood which may be elevated due to prostate cancer. However, high levels of PSA do not always indicate the presence of prostate cancer. Other prostate conditions such as enlarged prostate (benign prostatic hyperplasia) or inflammation of the prostate (prostatitis) can also increase PSA levels. PSA levels also increase with age. If PSA levels are elevated, it’s important to discuss your results with a healthcare provider.
