Gamma Knife Radiosurgery

Despite its name, Gamma Knife involves no knife and no cutting. It is the gold standard for Stereotactic Radiosurgery (SRS) used to treat small-to-medium brain tumors (like acoustic neuromas and pituitary adenomas), Arteriovenous Malformations (AVMs), and Trigeminal Neuralgia. Medical tourists seek this treatment because it offers the precision of surgery without the risks of open-skull operations, anesthesia, or long hospital stays. The Gamma Knife machine focuses precisely 192 intersecting beams of gamma radiation directly onto the target inside the brain. While each individual beam is too weak to harm healthy brain tissue on its path, the point where all 192 beams intersect delivers a massive, lethal dose of radiation that destroys the tumor's DNA, causing it to shrink and die over time.
