Germ Cell tumours come from the reproductive cells called Germ Cells. Germ Cell tumours mainly affect the ovaries in women, and the testes in men. They can also sometimes occur in the brain. Germ cell tumours are more common in young people.
Germ Cell Tumours start in the reproductive cells known as germ cells. Almost all testicular cancers start in the germ cells.
A germ cell tumour of the ovary is called an ovarian teratoma. It only affects females as the ovaries are female reproductive organs.
