Mapping the Burden
Recent population-level analyses make clear that a small number of infectious agents are responsible for most preventable cancer cases worldwide. The geography of that burden tracks closely with vaccine coverage, screening availability, and access to early treatment.
Translating this evidence into action means closing well-understood gaps — not waiting for new science.
The interventions that would prevent most of these cancers already exist. The challenge is deployment, not discovery.
Practical Prevention
Vaccination programmes, simple screening protocols, and timely treatment of precursor conditions are the levers that move the numbers. Progress depends on aligning health-system capacity, public-health communication, and sustainable financing.
