For primary tumors, surgical resection is the most common treatment modality. As for the deep-seated tumors which cannot be removed through traditional open surgery, gamma knife radiosurgery is another possible option.
For benign tumors, the probability of complete surgical resection is high, and the patient's survival rate is high as well. Without radiation or chemotherapy, the relapse rate is low. However, patient may still need diagnostic imaging tests such as CT or MRI. If the benign tumor could not be removed completely , the patient need closely follow-up, or to use chemotherapy, or radiation therapy accordingly.
For malignant brain tumor, if it can be completely resected or nearly completely resected, the prognosis is better. However, radiotherapy and/ or chemotherapy are still needed to control tumor growth.
