Gamma Knife is the most advanced radiosurgical tool available to treat a variety of brain lesions and disorders, including cancers of the brain. An alternative to invasive surgery, Gamma Knife Perfexion used at the Gamma Knife Center of Oregon focuses 192 independent beams of radiation on a single, precisely targeted location. With pinpoint accuracy, Gamma Knife can destroy tumors with no incisions, minimal blood loss and minimal damage to surrounding healthy tissue.
Meningiomas are benign, slow-growing tumors, classified as brain tumors but actually growing in the three protective membranes that surround the brain (meninges). Sometimes they cause thickening or thinning of adjoining skull bones. Meningiomas do not spread to other areas of the body.
