The statement that Gamma Knife surgery is not recommended has no scientific basis. Gamma Knife belongs to a kind of localized stereotactic radiation therapy, different from the ordinary large area irradiation, forming an effect similar to scalpel cutting, called Gamma Knife. Gamma Knife basically does not have much effect on the patient’s health. However, some patients may experience localized edema and some adverse reactions, such as nausea, vomiting, hair loss and poor appetite. The precision of Gamma Knife is relatively high, and the general error is only 0.1 millimeter, which can achieve the precision that is hard to reach by naked eyes. For small and deep benign tumors, Gamma Knife has good resection effect. Whether to choose Gamma Knife treatment needs to be judged under the guidance of professional doctors in regular hospitals and in conjunction with the patient’s condition.
