Meningioma is a spherical derivative of the interstitial meninges with a clear boundary to the brain tissue. The cause is unclear and may be related to genetic factors, cranio-cerebral trauma and other disease factors. Meningiomas are mostly benign tumors, but the possibility of malignancy cannot be ruled out. Whether meningioma is serious or not mainly depends on the nature of meningioma tumor and the size of the tumor.1. Not serious: If there are no previous symptoms and the tumor is found to be small (less than 2cm) on physical examination, regardless of the nature of the tumor, it usually has a good prognosis after standardized treatment, both benign and malignant tumors can be treated by surgical resection, but head surgery has certain risks and may lead to adverse reactions, so it is necessary to Therefore, it is necessary to choose an authoritative hospital and doctor. Benign tumors also need regular review after surgical resection, and malignant tumors should follow the doctor’s opinion whether to combine with radiation therapy to reduce the recurrence rate after surgery; 2. Serious: If it is a malignant tumor and there are obvious symptoms of increased intracranial pressure such as headache, nausea, vomiting, and optic disc edema in the fundus, it suggests that meningioma may appear to increase, which can seriously affect the patient’s quality of life and life expectancy, so it is recommended to go to hospital for treatment in time It is recommended to go to hospital for treatment. Treatment depends on the patient’s physical condition, tumor size and other factors. If the patient is physically able to tolerate surgery and surgical removal of the tumor is feasible, surgical removal should be performed, followed by radiotherapy to reduce the recurrence rate; if the tumor is too large, radiotherapy should be administered first to inhibit the tumor from developing, and then surgical removal should be performed after the condition is stabilized. If the tumor is in advanced stage, or combined with multiple metastases, so that surgery is not possible, symptomatic treatment should be chosen to maximize the survival quality of the patient.
