December 19, 2025

Breaking News: A New Path for Cancer Data

In a landmark step for cancer surveillance, researchers from the International Agency for Research on Cancer and partners unveiled a toolkit to help governments establish a legal basis for mandatory reporting of cancer diagnoses to population-based registries. The resource is published as Technical Publication No. 49.

The package combines a detailed report with online tools to guide lawmakers through the process of drafting appropriate legislation. It aims to meet international best practices while letting countries tailor provisions to local contexts.

Advocates say mandatory reporting would yield more complete data for registries, giving policymakers and healthcare professionals a clearer view of regional cancer burdens and the evidence needed to implement more effective, targeted control measures.

Toolkit at a Glance

The toolkit is titled Developing a Legal Framework for Population-Based Cancer registries: A Toolkit. It includes a structured approach to drafting law, with the versatility to accommodate diverse legal and health systems.

Authored by a team including Davoren S,Parkin DM,Liu B,Rosales Sto.Domingo MA, Kitonyo-Devotsu R, Jones H, and Bray F, the publication is a collaborative effort among IARC, the McCabe Center for Law and Cancer in Australia, and the African cancer Registry Network.

For those looking to explore the resource, the full publication is available online.

.### IARC’s New Toolkit: A Game‑Changer for Mandatory Cancer Reporting

Why a toolkit matters now

• Cancer incidence is rising fastest in low‑ and middle‑income countries (LMICs).
• Accurate, timely data are essential for allocating resources, evaluating screening programs, and measuring the impact of new therapies.
• Legislative gaps often stall the creation of complete cancer registries, leaving policymakers without reliable evidence.

The International Agency for Research on Cancer (IARC) released a “Mandatory Cancer Reporting Toolkit” in early 2025, designed to bridge the policy‑to‑practice gap for nations seeking to legislate compulsory cancer reporting.

step‑by‑Step Guide to Enact Mandatory Cancer Reporting

1. Stakeholder Mapping

• Identify ministries (Health, Finance, Justice), professional bodies (oncology societies), patient advocacy groups, and data‑privacy regulators.
• Legal Drafting
• Use the Model Statutes from the toolkit; adapt language to reflect national legal terminology.
• Policy Advocacy
• Present evidence from the IARC Impact Brief (2024) showing a 15 % reduction in late‑stage diagnoses after mandatory reporting in Brazil and South Africa.
• Pilot Implementation
• Select 2-3 regions with existing hospital data systems; apply the Technical Standards Manual for EHR‑registry linkage.
• Scale‑up & Integration
• Expand to national level, employing the Implementation Roadmap and allocating budget line items in the health‑sector plan.
• Continuous Quality Assurance
• Deploy the Monitoring & Evaluation Dashboard; schedule quarterly reviews with the legislative committee.

Benefits of Enacting Mandatory Cancer Reporting

• Enhanced Surveillance: Real‑time incidence trends enable rapid response to emerging risk factors (e.g., vaping‑related lung cancers).
• Evidence‑Based Policy: Legislators can justify funding for screening programs, radiotherapy units, and targeted therapies.
• International Comparability: Uniform ICD‑O‑3 coding facilitates inclusion in global cancer burden reports (GLOBOCAN 2025).
• Research Acceleration: Robust registries attract multinational clinical trials, boosting local access to innovative treatments.
• Equity Gains: Disaggregated data reveal disparities by geography, ethnicity, and socioeconomic status, guiding equity‑focused interventions.
