The first choice of treatment for brain tumor is surgery, because only through surgery to remove the tumor can pathological examination of the tumor be conducted to clarify the nature of the tumor and the characteristics of the tumor cells, and only then can the next step of treatment be carried out. In addition to surgery, the main treatment methods for brain tumors are: 1) conventional radiation therapy, which is mainly applied to tumors sensitive to radiotherapy, including germ cell tumors, medulloblastoma, and lymphoma; 2) intra-tumor radiation therapy, which means injecting radioactive drugs into the tumor cavity and relying on the ionizing radiation of gamma rays or beta rays emitted by the radioactive drugs to kill the tumor; 3) stereotactic radiation therapy, which is also known as stereotactic radiation therapy. Radiotherapy, which is also known as γ-knife and X-knife; 4. Chemotherapy, which is only suitable for tumors sensitive to chemotherapy, including germ cell tumors and lymphomas; 5. Immunotherapy, gene therapy, phototherapy, as well as Chinese medicine and traditional Chinese medicine, etc., but the efficacy of these methods is not exact at present and needs to be further explored.
