There is no authoritative information on how long brainstem gliomas typically grow before symptoms develop; patients with fast-growing brainstem gliomas may develop symptoms weeks or before 1 year. If the patient’s glioma is growing slowly, symptoms usually appear after 1 year. How soon a patient develops symptoms from a brainstem glioma is related to the pathologic staging. In the case of high-grade (malignant) gliomas, which grow at a rapid rate, patients may experience symptoms such as severe headaches and projectile vomiting in a matter of weeks or months. In the case of low-grade brainstem gliomas, the patient’s tumor grows slowly, and most patients experience symptoms as early as 1 year after developing the disease. Patients with brainstem glioma need to seek medical treatment in time, and doctors will determine the appropriate treatment measures according to the patient’s condition. In addition, patients usually need to ensure enough rest, avoid staying up late, keep a good mood, and eat fresh fruits and vegetables, such as apples, oranges, green vegetables, carrots and so on.
