Prostate Cancer
The prostate gland is part of the internal structure of the male reproductive system. Cancer of the prostate is common (50 percent of men over age 70 get cancer of the prostate), grows slowly, and ranks third among the types of cancers that kill American men. The cancer can metastasize (spread) to other organs during its advanced stages

Testicular Cancer
The testes (or testicles) are part of the external male reproductive system. If they are attacked by cancer, a hard and often painful lump will be noticed in the scrotum (the thin-skinned sac that protects the testes). Most testicular cancers occur in men over 40 years old.
