There is no such thing as benign glioma, glioma belongs to a malignant tumor disease, the condition is usually more serious. Glioma is the most common primary intracranial tumor, the etiology is still unclear, but it is not a benign disease, so there is no benign glioma, once the glioma appears, it is a malignant disease. Gliomas are classified into 1~4 grades, among which 1~2 grades belong to low-grade gliomas, and the prognosis is relatively good if they are completely removed by surgery. Grades 3 to 4 are high-grade gliomas with a poor prognosis. Glioma needs to go to the hospital to do neurological physical examination and CT, MRI examination, and need to do pathological puncture biopsy to determine the disease, after the diagnosis of timely targeted therapeutic measures.
