As the premier radiation oncology society in the world, the American Society for Radiation Oncology (ASTRO) represents more than 10,000 members — physicians, physicists, biologists, radiation therapists, dosimetrists, nurses and other health care professionals dedicated to treating cancer with precision and compassion.
Together, these multidisciplinary teams care for over one million cancer patients each year in hospitals, cancer centers, and academic research institutions across the globe.
Through ASTRO and its philanthropic foundation, we are united by a shared mission:
- To advance research and innovation in radiation medicine
- To support education and training for professionals at every level
- To advocate for equitable access to high-quality radiation therapy
- And to improve patient outcomes through evidence-based care
