PSA Testing

PSA stands for Prostate Specific Antigen. This is a protein produced by the prostate. It is measured by taking a blood sample. Different age groups have different PSA levels within the blood.

In most cases, malignant or cancerous prostate tissue produces more PSA than non-malignant or benign prostate tissue. The test does, however, have limitations and other non-cancerous conditions can result in a high PSA level.

In combination with an examination of the prostate, the PSA level can help the surgeon determine the likelihood of prostate cancer being present. 

This may lead to the surgeon recommending a prostate biopsy to see if any cancer is present.
