Founded in 1958, ASTRO's mission is to advance the practice of radiation oncology by promoting excellence in patient care, providing opportunities for educational and professional development, promoting research and disseminating research results and representing radiation oncology in a rapidly evolving healthcare environment.
　Within the specific field of radiation oncology, we provide our members with numerous educational and professional development opportunities - from sponsoring hands-on educational courses year round to sponsoring the premier radiation oncology research journal, International Journal of Radiation Oncology*Biology*Physics.
　ASTRO also focuses on fostering collaboration between radiation oncologists and the larger medical community. We work to establish links between our members and medical oncologists, surgeons, urologists, gynecologists, internists, family practitioners and other healthcare professionals to ensure that patients are offered the most up-to-date treatments available.
　To better educate the patients that our members work so hard to cure, ASTRO works closely with the media to promote accurate articles on scientific breakthroughs involving radiation therapies. We also work with patient advocacy organizations to publish educational materials that keep patients and the public informed about radiation therapy as a safe and effective treatment option.
