American Society for Radiation Oncology

What American Society for Radiation Oncology does

ASTRO (American Society for Radiation Oncology) is a 501(c)(6) nonprofit professional medical society founded in 1958 and headquartered in Arlington, Virginia. It serves more than 10,000 members across the radiation oncology profession, including radiation oncologists, medical physicists, dosimetrists, radiation therapists, nurses, biologists, physician assistants, practice administrators, and industry representatives. The society operates a comprehensive portfolio centered on clinical practice guidelines, peer-reviewed publications (Red Journal, Practical Radiation Oncology, and Advances in Radiation Oncology), the APEx facility accreditation program (nearly 500 facilities accredited), the RO-ILS incident learning system (500+ facilities enrolled), the ASTRO Academy online learning platform, the RO*hub* member community, and the RTAnswers public-facing patient resource.

Its technology footprint includes online learning and accreditation portals, a legally protected safety incident reporting system, member networking infrastructure, and an Epic EHR integration that delivers patient education content directly into clinical workflows. Business model revenue is generated across five streams: recurring membership dues, registration and sponsorship revenue from the flagship annual meeting and multiple specialty symposia, sales of educational products and publications through the product catalog and journals, and educational grants from industry partners such as Novartis Pharmaceuticals Corp. The society also operates ASTRO PAC, a federally regulated political action committee supporting advocacy on reimbursement, prior authorization reform, and workforce policy, with a recent strategic pivot toward radiopharmaceutical therapy training and accreditation to address a documented workforce gap in that fast-growing modality.

Direct peers

• American Society of Clinical Oncology (ASCO): The largest U.S. professional society for oncology clinicians. Highly comparable as a medical specialty society that runs an annual meeting, journals (JCO), educational accreditation, advocacy, and member dues — only serving the broader oncology rather than radiation oncology specialty.
• European Society for Radiotherapy & Oncology (ESTRO): The European counterpart to ASTRO, focused on radiation oncology, radiotherapy, and clinical oncology. Closest international peer in mission (radiotherapy society) with comparable meetings, journals (Radiotherapy & Oncology), and educational programming.
• American Association of Physicists in Medicine (AAPM): The U.S. professional society for medical physicists — a core constituency within ASTRO's membership. Comparable as a specialty society with annual meetings, journals, accreditation, and advocacy for a radiation oncology-adjacent profession.
• American Brachytherapy Society (ABS): U.S. society for brachytherapy practitioners, a subspecialty of radiation oncology. Comparable structure (society, annual meeting, journal, guidelines, member education) but narrower scope.
• Society of Nuclear Medicine & Molecular Imaging (SNMMI): Professional society for nuclear medicine — directly relevant given ASTRO's growing radiopharmaceutical therapy focus. Comparable model (society, journals, annual meeting, guidelines, advocacy) with overlapping clinical territory in theranostics and PET.
• American College of Radiation Oncology (ACRO): Smaller U.S. radiation oncology society that historically competed with ASTRO on accreditation (ACRO accreditation) and practice advocacy. Closest direct competitor in the U.S. radiation oncology society landscape.

Broad incumbents

• American College of Radiology (ACR): Larger, broader radiology professional society with accreditation (ACR accreditation is widely adopted), practice standards, advocacy, and journals (JACR). Comparable governance and policy muscle, with overlapping membership in imaging-focused radiation oncology practices.
• Radiological Society of North America (RSNA): Major radiology society running one of the world's largest medical meetings (RSNA Annual Meeting) and publishing Radiology. Comparable in scale of meeting, journals, and education, but serves the broader diagnostic-imaging specialty.
• American Medical Association (AMA): The umbrella U.S. physician professional association. Comparable in advocacy, education, and member services model, but at a much broader scope across all medical specialties rather than radiation oncology specifically.

Emerging players

• National Comprehensive Cancer Network (NCCN): Alliance of leading cancer centers that publishes widely used oncology clinical practice guidelines and runs educational programs. Comparable as a guideline- and education-driven oncology organization whose NCCN Guidelines frequently reference radiation oncology protocols developed by ASTRO.
