Types of Germ Cell Tumors

  • Germ cell tumors are masses of tissue formed by immature cells that normally would have developed into mature eggs (in a female) or sperm (in a male). Although germ cell tumors are rare in children under age 15, they are the most common solid tumors in adolescents, accounting for 14% of all cancers among those 15-19 years old.

    Germ cell tumors usually develop in the ovaries or testes. However, they can appear in other parts of the body, including the abdomen, chest, neck, head or brain.
