An 80-year-old man with meningioma does not necessarily need to be operated on. If there are no symptoms, he can be temporarily observed and regularly rechecked. If the disease continues to develop or obvious symptoms appear, then you should choose surgery to treat it according to your own situation. Whether it is necessary to operate for 80-year-old man with meningioma depends on the actual situation, and cannot be generalized, but mainly depends on the severity of the disease and the patient’s own physical condition. For benign meningiomas with size less than 2 cm and no clinical symptoms, close observation and regular checkups can be done for the time being. Usually, meningiomas grow slowly and do not require immediate surgical treatment. However, for malignant meningiomas, meningiomas with progressive increase in size, or meningiomas with clinical symptoms such as headache, nausea, vomiting, etc., surgery is necessary. In addition, radiation therapy is also available for patients who cannot tolerate surgery. All in all, doctors will formulate appropriate treatment plans according to the overall conditions of the meningioma patients, and the patients need to actively cooperate with doctors for treatment.
