What is testicular cancer?
Testicular cancer begins in one or both of the testicles. The testicles are located in the scrotum, the skin “sack” that hangs beneath the penis. Hormones and sperm are produced in the testicles. A normal adult testicle is about the size of a golf ball and is round, smooth and firm.
