Glioma malignant grade 3 is more serious. According to pathological grading, gliomas can be divided into grades 1~4. Grade 3 gliomas are high-grade gliomas with unclear borders with surrounding tissues and infiltrative growth, which are difficult to be completely removed and have the possibility of recurrence after surgery.The median survival of patients with grade 3 gliomas is usually between 3~4 years. Gliomas are common malignant tumors within the brain and skull. Gliomas are difficult to eradicate, have a rapid disease progression, are prone to recurrence after surgery, and have a poor prognosis. With the development of the disease, glioma may show symptoms of increased intracranial pressure, which may lead to severe symptoms such as optic papillae edema, vomiting, autonomic function changes, hemiparesis, and blindness on one side of the body, and therefore it is a more serious disease. It is suggested that glioma patients should seek medical treatment in time and under the guidance of doctors, so as to avoid delaying the condition and causing serious consequences.
