Description:
A protein that is usually found on the surface of normal prostate cells but is found in higher amounts on prostate cancer cells. PSMA may be used as a target in imaging to help find prostate cancer cells, especially those that may have come back or spread to other parts of the body. Research is being done to learn more about PSMA and how it may also be used as a target for certain anticancer drugs. Also called prostate-specific membrane antigen.
