Brain tumors are divided into benign tumors and malignant tumors, both of which can now be treated by surgery. The prognosis of benign tumors is better after surgery, while malignant tumors are usually treated with radiotherapy after surgery, and the prognosis is related to the degree of malignancy, tumor size and other factors. Patients with benign tumors have good prognosis after surgical resection, including pituitary tumor, meningioma, cholesteatoma, and auditory neuroma, etc.; low-grade malignant tumors are treated with radiotherapy and chemotherapy after surgical resection, which have higher cure rate and do not affect life expectancy; tumors with relatively higher malignancy tend to have poorer prognosis. The prognosis of these tumors needs to be evaluated by a specialist according to the condition. In conclusion, brain tumors can be treated, but the cure rate is closely related to the type and condition of the tumor.
