Diffuse glioma is an intracranial tumor originating from glial cells, and is the most common primary intracranial tumor, mostly more serious. Diffuse glioma is a relatively serious disease, and patients often experience a series of symptoms, such as headaches, epilepsy, visual impairment, speech disorders, and so on, which seriously affects their daily lives. So far, there is no cure for this disease, and it can only be treated by surgery combined with radiotherapy to alleviate the symptoms and slow down the progression of the disease. Diffuse glioma is prone to recurrence after surgical resection, and the disease progresses faster after recurrence, resulting in a poorer prognosis. It is recommended to consult a doctor as soon as possible after diagnosis of diffuse glioma, and actively treat the disease under the doctor’s guidance in order to maximize the improvement of the prognosis.
