UW-Health Offers GammaTile Brain Tumor Treatment
The radiation-releasing tiles are placed in the surgical site after tumor removal to target cells that may remain.
Updated on Nov. 11, 2026 in Cancer
UW-Health has begun offering GammaTile, a brain tumor treatment developed by GT Medical Technologies of Tempe, Arizona. The health system performed the first GammaTile procedure last month.
Why it matters
The treatment targets tumor cells that surgery may leave behind, concentrating radiation near the removal site. It adds an option for brain tumor patients in the Madison area.
The source extraction contains no clinical statistics for GammaTile. Patient outcomes and the number of procedures performed since the first case were not reported.
The players
UW-Health
The University of Wisconsin health system, which began offering GammaTile and performed the first procedure with the treatment.
GT Medical Technologies
A medical technology company based in Tempe, Arizona, that developed the GammaTile brain tumor treatment.
The details
After surgeons remove a brain tumor, they place absorbable tiles containing radioactive seeds in the space where the tumor was. The radiation begins working immediately to target tumor cells that may be left behind, and the approach concentrates radiation near the surgical site.
Timeline
UW-Health performed the first GammaTile procedure last month, in October 2026.
Health Landscape
GammaTile is a localized radiation option delivered at the time of surgery, rather than as a separate course of treatment afterward. Its arrival at UW-Health adds a surgical-site radiation tool to the brain tumor care available in Madison.
Patients with brain tumors who undergo surgery may be offered GammaTile as an additional treatment step at UW-Health. The tiles are placed during the same operation that removes the tumor.
The takeaway
Patients facing brain tumor surgery can ask their care teams whether localized radiation placed during the operation is an option. Treatment availability depends on the individual case and the surgical team's assessment.
