Treatment of Seminoma

For information about the treatments listed below, see the Treatment Option Overview section.

Treatment of seminoma extragonadal germ cell tumors may include the following:

• Radiation therapy for small tumors in one area, followed by watchful waiting if there is tumor remaining after treatment.
• Chemotherapy for larger tumors or tumors that have spread. If a tumor smaller than 3 centimeters remains after chemotherapy, watchful waiting follows. If a larger tumor remains after treatment, surgery or watchful waiting follow.
