Most gliomas, once discovered, should be operated on as soon as possible if the patient is physically able, including biopsy or tumor resection, to clarify the pathological nature after surgery, and if further treatment is needed, radiotherapy should be done as early as possible to prolong the patient’s survival. In some patients, glioma is not particularly typical, so you can choose to observe it for a period of time and then review it. If the MRI review indicates that the lesion has increased in size, surgery should be performed as early as possible to clarify the pathological nature, and if it is a glioma, comprehensive treatment such as radiotherapy should be done as early as possible. Some gliomas may be low grade II tumors at the time of discovery, but they may gradually increase in size during the observation period, and may transform to high grade. Once they become interstitial or grade IV glioblastoma, they may progress rapidly within a short period of time, and if this happens, even if surgery is performed in time, the survival period will be shortened, and the risk of surgery will increase.
