One kind of radiation treatment is called gamma knife radiosurgery. Another name for it is stereotactic radiosurgery. Despite being named surgery, a Gamma Knife operation does not involve making any incisions. It's not a knife, either. With a Gamma Knife, a lesion or tumor can be treated with extremely focused gamma ray beams. The brain uses it the most frequently. Without requiring an incision, the gamma radiation beams deliver an extremely high dosage of radiation to a limited area. Radiosurgery stops cells from proliferating by destroying them. Over time, a lesion or tumor will get smaller.

Gamma Knife radiosurgery a kind of “minimally invasive surgery”, is used for treating brain tumors, abnormal blood vessels, and other cerebral anomalies. Unlike conventional surgeries, it doesn't involve incisions. Instead, it employs numerous precise radiation beams focused on the target area, minimizing the impact on surrounding healthy tissue while delivering a potent radiation dose to the focal point. This accuracy ensures minimal radiation exposure to nearby healthy tissues.it is generally completed in a single session, Gamma Knife radiosurgery offers efficient treatment with reduced risk to surrounding structures.
Gamma Knife radiation is for treating brain lesions and inoperable tumors by delivering precise doses of radiation to the targeted area. Post-procedure, the lesion is anticipated to shrink, disintegrate, or cease further growth. This form of radiosurgery is utilized for various conditions including primary or metastatic brain cancers, benign tumors like meningioma and pituitary adenomas, vascular malformations such as arteriovenous malformations, and functional disorders like trigeminal neuralgia.
