Brain malignant tumors can be treated, and for most brain malignant tumors, surgery is the first choice of treatment because surgery can remove the tumor and conduct pathological examination of the removed tumor to determine the nature of the tumor and the characteristics of the tumor cells, which will provide the basis for the next step of treatment. In addition to surgical treatment, brain malignant tumors can also be treated with radiation therapy and chemotherapy according to their pathological nature, of which radiation therapy includes local conventional radiation therapy, as well as intra-tumor radiation therapy, and radiation therapy under stereotactic orientation. In addition to radiotherapy and chemotherapy, there are some other therapies, including immunotherapy, targeted drug therapy, gene therapy, traditional Chinese medicine and so on, but the effect of these therapies is not exact.
