Gliomas are the most common primary malignant tumor of the brain, meaning cancers that start in the brain. Gliomas include glioblastoma, astrocytoma, oligodendroglioma, ependymoma, and other similar tumors. Gliomas can occur in any area of the brain. Gliomas can cause different symptoms depending on where they are located in the brain.
Treatment options for gliomas include surgery, laser ablation therapy (LITT), radiation, chemotherapy, targeted drugs, and tumor treating fields. Gliomas range from very slow growing to very fast growing. Optimizing treatment requires knowing the type of glioma, the molecular features of the glioma, the location in the brain, and the attributes of the person.
