The effect of gamma knife on brain tumor

Gamma-knife

is a stereotactic radiosurgery method, which has many advantages for brain tumor treatment. It has a high degree of accuracy. It can accurately focus on the tumor lesion, causing less damage to surrounding normal tissues, thus reducing post-treatment complications. This is because Gamma-knife uses gamma rays emitted by multiple cobalt-60 sources to focus high-energy rays on the tumor area through precise positioning and focusing system, achieving precise impact on the tumor. GammaKnife provides an effective alternative treatment for brain tumors that are not suitable for surgery or patients who are unwilling to undergo surgery. For example, GammaKnife can control tumor growth to a certain extent and relieve symptoms for brain tumors that are deep, difficult to operate or patients with poor physical condition cannot tolerate surgery.

GammaKnife treatment is usually a one-time treatment, which requires multiple treatments compared with traditional radiotherapy, reducing the treatment time and burden for patients. Patients do not need to experience long hospitalization and multiple trips to the hospital, improving the convenience of treatment.

However, GammaKnife treatment is not suitable for all brain tumor cases. For large and highly malignant brain tumors, it may be necessary to combine other treatments such as surgery and chemotherapy to achieve better treatment results. At the same time, close follow-up observation is required after treatment to monitor tumor changes and possible adverse reactions.
