Prostate cancer is a life-threatening tumor that develops in the prostate.
The prostate is a gland in men within the pelvis at the base of the penis. It surrounds the bottom part of the bladder and urethra. The prostate produces a fluid that nourishes sperm and is ejaculated with semen, the fluid that carries sperm. Prostate cancer is the most common cancer in American men. Two to three times more African-American men get prostate cancer than white men.
