Prostate specific antigen (PSA) is an enzyme produced by the prostate gland. Normally, PSA is secreted in small amounts into the bloodstream. However, larger amounts of PSA are released when the gland is enlarged, infected or diseased. The level of PSA in the blood can be determined by a simple blood test done here in our office.

A reading between 0.00-4.00 is considered “normal”, although PSA levels vary from man to man, asMarta well as with race and age. A reading between 4.00 – 10.00 is usually due to a benign enlarged prostate, but it can be suspicious for cancer. A reading higher than 10.00 may also be just benign prostate disease, but the higher the PSA the more likely it is to be cancer. If your PSA level is elevated, or you have other suspicious problems, your doctor might recommend a prostate biopsy for further diagnostic testing.

A PSA blood test can also be used to monitor your prostate cancer treatment or to decide whether you need treatment. If your PSA is stable, it is a sign that your cancer is not progressing. Successful treatment shrinks cancer and so the PSA level falls.
