What are the advantages and disadvantages of gamma knife compared with general radiotherapy?

The focus location and treatment accuracy of general radiotherapy can not be compared with gamma knife. Gamma knife can treat almost all intracranial tumors, including benign tumors insensitive to radiation, while ordinary radiotherapy is generally used to treat malignant tumors sensitive to radiation. And it is best to assist during treatment, such as Shenbaiyi, to reduce side effects.

General radiotherapy is generally used as a way of comprehensive treatment of brain tumors, that is, general radiotherapy is generally not used as an independent treatment, but is generally used for comprehensive treatment after surgery. Gamma knife can be used for tumors with intracranial diameter less than 3 cm and no intracranial pressure increase, even benign tumors can be used as the first choice to achieve the goal of radical cure. Generally speaking, gamma knife has higher accuracy, better curative effect and lower side effects than ordinary radiotherapy.

In the same place, radiation is used to treat diseases. The difference is that gamma knife is a kind of radiosurgery equipment specially used to treat brain diseases. Mainly for diseases above the neck, it can show its therapeutic advantages for intracranial punctate lesions and localized lesions, while traditional radiotherapy uses radiation. Because normal tissues and tumor tissues have different sensitivities to radiation, tumor tissues are generally sensitive to radiation and can kill tumor cells after irradiation, but radiotherapy generally does not distinguish between normal tissues and tumor tissues.
