General Information
Note: Separate PDQ summaries on Ovarian Germ Cell Tumors Treatment 1 and Testicular Cancer Treatment 2 are also available.
Extragonadal germ cell tumors are rare and account for only a small percentage
of all germ cell tumors. However, the true incidence of these tumors may
conceivably be higher than originally thought because of failure to diagnose
them properly.
