This test is intended for use as an aid in the management of individuals following surgical or medical treatment of prostate cancer. Prostate specific antigen (psa) is a protein produced only by the prostate gland. The prostate gland is a doughnut-shaped gland located in a man's pelvis in the small space between the base of the penis and the bladder. The prostate makes the fluid that nourishes sperm and carries sperm during ejaculation. The amount of psa produced by the prostate gland can be helpful in detecting prostate cancer very early. If you have prostate cancer.psa is an important tool for following the progress of the cancer.
