What type of therapy is Gamma Knife therapy categorized as?

Gamma Knife therapy is categorized as radiation therapy because it utilizes focused radiation beams to target and treat abnormal growths in the brain, such as tumors or vascular malformations. This technique delivers a high dose of radiation precisely to the area needing treatment while minimizing exposure to surrounding healthy tissue. The procedure does not involve any surgical incisions, hence it is distinct from surgical therapies, which typically involve physically removing or altering tissue.

By delivering ionizing radiation to the targeted area, Gamma Knife therapy aims to shrink tumors or allow them to stop growing without the need for traditional surgery, thereby reinforcing its classification strictly under radiation therapy.
