THE RADIATION ONCOLOGY INSTITUTE

Radiation therapy is used to treat more than one million cancer patients each year. Yet, funding for radiation oncology research is limited.

ROI advances research and education so that patients with cancer can receive high-quality, innovative radiation treatment that enhances their quality of life and ultimately, saves more lives.

Founded in 2006 by the American Society for Radiation Oncology (ASTRO), ROI is a 501(c)(3) charity that has funded $4.3 million in research to improve outcomes for cancer patients and drive the field of radiation oncology forward.
