GammaTile is an innovative form of radiation therapy placed at the time of tumor removal surgery, delivering immediate, targeted radiation to the tumor site when cancer cells are at their lowest levels. Unlike conventional approaches, which often require a delay between surgery and radiation therapy to allow for wound healing, GammaTile eliminates this treatment gap. By delivering immediate, localized radiation directly at the tumor site, it is designed to maximize the treatment's effectiveness against remaining cancer cells and reduce the risk of regrowth.¹

GammaTile is FDA-cleared for newly diagnosed malignant (cancerous) and recurrent brain tumors and has been adopted by more than 150 leading centers across the United States, underscoring its growing acceptance in both academic and community healthcare settings.² For more information, visit gammatile.com and follow @GammaTile on, Facebook, Instagram, LinkedIn and X.
