Testis or testicular cancer is a disease in which malignant (cancer) cells form in the tissues of one or both testicles, the male sex glands, which produce the hormone testosterone and male reproductive cells or sperm. Almost all testicular cancers start in the germ cells responsible for producing immature sperm. The two main types of testicular germ cell tumors are seminomas and nonseminomas. These two types grow and spread differently and are treated differently.
The following are resources from the National Cancer Institute for testis cancer:
