Risk Factors of Childhood Extracranial Germ Cell Tumor
These tumors get their start while the child is still in the mother’s womb, very early in pregnancy. Cells that are designed to form the reproductive system break away and travel to other parts of the body. Later in the child’s life, they can develop into tumors. There is no way to prevent this disease.

Constipation
Urinary retention
For boys: painless swelling or mass in the testicles
For girls: abdominal pain

CT (or CAT) Scan
Biopsy
Blood tests
Pelvic exam
