Metastatic prostate cancer is prostate cancer that has spread (metastasized) to the lymph nodes or other parts of the body. Prostate cancer is the abnormal growth of cells in the tissues of the prostate gland. The prostate is part of the male reproductive system. It is a small organ below the bladder that makes fluid for semen.

Treatment for metastatic prostate cancer focuses on relieving symptoms and slowing the rate at which the cancer spreads.
