About the ROI
The Radiation Oncology Institute (ROI) is a nonprofit foundation working to heighten the critical role of radiation therapy in the treatment of cancer through research and education. Founded in 2006 by the American Society for Radiation Oncology (ASTRO), the ROI is an affiliated 501(c)(3) organization established to support research and education about the life-saving and quality-of-life benefits of radiation therapy. The ROI relies on tax-deductible donations made by generous donors like you to carry out our mission.
Following an initial period to establish resources and an endowment, the ROI has funded $3.2 million in research in priority topic areas to improve outcomes for patients and advance the field of radiation oncology.
