The prostate is a small structure located at the base of the penis, in front of the rectum and below the bladder. It surrounds the urethra that carries urine and semen. Its function is to make seminal fluid. When a malignant tumor is present, treatment is required. Prostate cancer is one of the more treatable cancers because it is slow growing.
Most cancers of the prostate are detected through a combination of physical examinations and diagnostic tests including: a rectal exam, blood tests for prostate-specific antigens (PSAs) and biopsies. It is especially important for men over 60 to have a regular prostate examination.
