What ESTRO does
ESTRO (European Society for Radiotherapy and Oncology) is a Belgian non-profit scientific organization (AISBL) founded in 1980, headquartered at Avenue Marnix 17 in Brussels, and serving more than 10,000 radiation oncology professionals globally. Its membership spans radiation oncologists, medical physicists, radiobiologists, and radiation therapists (RTTs) across Europe, Asia-Pacific, and the Americas, and it operates as the principal European professional society in the field. The organization is led by CEO Alessandro Jacques Cortese and governed through a member-elected Board; revenue is not publicly disclosed.
The society's product surface centers on three programmatic pillars: the ESTRO Congress (annual flagship, e.g., ESTRO 2027 in Milan; regional ESTRO Meets Asia 2026 in Singapore), ESTRO Workshops (specialized events such as the GEC-ESTRO Workshop and ESTRO Physics Workshop), and the ESTRO School (systematic curriculum of basic, multidisciplinary, treatment planning, imaging, contouring, and on-demand courses). Supporting infrastructure includes MyESTRO (member portal), ESTRO Moodle (LMS for course delivery), ESTRO HUB (digital platform for webinars and on-demand content), and FALCON (a contouring homogeneity project built on the EduCase platform). ESTRO publishes the Radiotherapy & Oncology journal ("Green Journal") through a partnership with Elsevier, and its programs are accredited by ACOE, EACCME, EBAMP, and recognized by the AMA.
Revenue is generated through four streams: multi-tier membership subscriptions (Free Undergraduate up to €250/year Supporting Ambassador), course and event registrations tiered by membership status and registration timing (€100-€950 per course), exhibition and sponsorship packages at congresses and workshops, and €55/year joint memberships with international partner societies (AAPM, AROI, JASTRO, SBRT, SEAROG, SOMERA). Distribution occurs via direct online sales through estro.org, in-person events, the Moodle/HUB digital platforms, and reseller-style relationships with national societies through the RTT Alliance (30+ national societies) and the Best of ESTRO Webinars Programme. All fees carry 21% Belgian VAT; solidarity grants of up to €1,500 and a €30,000 annual Educational Travel Grants budget support access from emerging countries.

ESTRO competitors and assessment
Company assessmentDirect peers
- American Society for Radiation Oncology (ASTRO): ASTRO is the leading U.S. professional society for radiation oncologists, medical physicists, and RTTs, offering the most direct functional mirror to ESTRO in Congress, School, journal (Red Journal/International Journal of Radiation Oncology), and accreditation-driven CE. It is the strongest 1:1 peer by mission, scope, and member services.
- Canadian Association of Radiation Oncology (CARO): CARO serves Canadian radiation oncologists with annual scientific meetings, CME, and a journal (Journal of Medical Imaging and Radiation Sciences collaboration). It mirrors ESTRO's national-society function but for Canada, with comparable educational programming and accreditation focus.
- Royal Australian and New Zealand College of Radiologists (RANZCR) - Faculty of Radiation Oncology: RANZCR's Faculty of Radiation Oncology sets training curriculum, conducts exams, and runs an annual scientific meeting for Australian/NZ radiation oncologists. Comparable to ESTRO in credentialing authority and educational program depth, with a more formal specialty college structure.
- Japanese Society for Radiation Oncology (JASTRO): JASTRO is ESTRO's joint-membership partner and the dominant Japanese radiation oncology society, running an annual congress and postgraduate courses with virtually identical scope (radiation oncologists, medical physicists, RTTs). It is a direct peer with parallel educational offerings for a national membership.
- Association of Radiation Oncologists of India (AROI): AROI is ESTRO's joint-membership partner and India's primary radiation oncology professional body, with an annual conference and CME-accredited courses comparable in scope and structure to ESTRO's national-society peers. It reflects the South-Asian, high-volume radiotherapy market where ESTRO has explicit channel reach.
- Sociedade Brasileira de Radioterapia (SBRT): SBRT is the Brazilian radiation oncology society and an ESTRO joint-membership partner, running a national congress and training programs. It is a direct Latin American peer by mission and represents an important channel for ESTRO content into the LatAm radiotherapy community.
Broad incumbents
- European Society for Medical Oncology (ESMO): ESMO is Europe's leading medical oncology society serving a parallel (and overlapping) cancer-care specialty with congress, journal (Annals of Oncology), and accreditation programs. While not radiation-specific, ESMO is the most relevant adjacent incumbent and the natural cross-specialty partner for multidisciplinary oncology training that ESTRO increasingly participates in.
- European Society of Radiology (ESR): ESR is the European professional society for radiologists with annual congress (ECR), journal (European Radiology), and educational programs. It is a peer in the imaging-adjacent cancer-care specialty space and a likely collaborator/competitor for multidisciplinary imaging-and-radiotherapy training content ESTRO delivers.
- European Cancer Organisation (ECO): ECO is a pan-European umbrella federation of oncology societies that engages in policy, advocacy, and multidisciplinary education across cancer care. It overlaps with ESTRO's advocacy role around Vision 2030-style radiotherapy access goals and convenes many of the same stakeholder communities, making it a structurally comparable incumbent in the European oncology ecosystem.
Others
- International Atomic Energy Agency (IAEA): IAEA runs radiotherapy capacity-building, training, and audit programs (including a seat on ESTRO's Education Council). It is not a member society but the most institutionally relevant comparator in radiation oncology education and a key partner in low- and middle-income country training—shaping demand for ESTRO's emerging-country offerings.
