PSA is a protein made by prostate cells. The prostate is part of the male reproductive and urinary systems. PSA is mostly found in semen, which is also made in the prostate, but small amounts of PSA can also be found in the blood. Higher levels of PSA in the blood can be caused by prostate cancer, among other things.
