Chemotherapy uses drugs circulated through the blood stream to destroy cancer cells. It is used if the cancer has spread outside the testicle. It can also be used after surgery if the tumor was not confined to the testicle, to destroy any cancerous cells left behind and prevent recurrence of the cancer. Most chemotherapy for testicular cancer is injected intravenously.
Your doctor may recommend External Beam Radiation Therapy (EBRT) as the primary treatment for seminoma germ cell tumors or in conjunction with surgery such as an orchiectomy, where the testicle is removed. Seminoma germ cell tumors are very sensitive to radiation therapy and this helps to prevent recurrence of the cancer. EBRT is not commonly used for non-seminoma germ cell tumors because they are not sensitive to radiation. Radiation can also be used if the cancer has spread beyond the testicle to treat the area of the lymph nodes.
