How long can one live after glioma grade 4 surgery is related to many factors such as the size of the tumor, whether it is treated in time, and the growth site, etc. Most of the patients have a survival period of 1~2 years after surgery, but the specific situation varies from person to person. If the glioma occurs in the cerebral hemisphere, there may be headache, vomiting, optic papilla edema and other symptoms. In the early stage, surgery should be performed as soon as possible, and after the surgery, radiotherapy, chemotherapy, electric field treatment and other methods can also be used, and the survival period of the patients after the surgery is usually around 1~2 years. If the glioma occurs in the brain stem and other important parts, it is often difficult to remove completely and easy to damage the important nerves, and it is also easy to recur after the operation, so the survival period may be relatively shorter, often less than 1 year, or even shortened to about 3~4 months. Therefore, if glioma is detected, it is recommended to seek early medical treatment to avoid delay.
