Surgery is an option when suffering from mediastinal germ cell tumor. If surgery is not possible, radiotherapy and chemotherapy are needed to control the recurrence and metastasis of the cancer. Mediastinal germ cell tumors are more malignant than germ cell tumors occurring in the ovaries, testes and other reproductive glands, and are prone to recurrence and metastasis. If mediastinal germ cell tumor is detected at an early stage, it can be evaluated under the guidance of a doctor, and surgical resection is the first choice of treatment, after which appropriate radiotherapy and chemotherapy programs will be selected according to the pathological staging. If distant metastasis of mediastinal germ cell tumor occurs, it is necessary to cooperate with systemic chemotherapy to control the progression of the disease and prolong the survival time. After suffering from mediastinal germ cell tumor, it is necessary to be under the guidance of professional doctors, through the relevant examination, to clarify the appropriate treatment plan, and actively treat it.
