Testicular cancer occurs when cells that are not normal grow out of control in the testicles (testes). It’s highly curable, especially when found early. The testes are the two male sex organs that make and store sperm. They are located in a pouch below the penis called the scrotum. The testes also make the hormone testosterone.
Testicular cancer is most common among white males. It’s not common in men of African or Asian background. Although rare, testicular cancer is the most common form of cancer in men between the ages of 20 and 34. Experts don't know what causes testicular cancer, but some problems may increase your chances of getting it.
