Overview
- Drees published the analysis on Thursday, June 4, 2026, using linked Assurance Maladie reimbursement records and an Insee demographic sample covering 2013–2020 to measure cancer incidence, stage at diagnosis and prognosis by socioeconomic decile.
- The study reports large gaps: men in the poorest 10% had about 2.2 times the risk of lung cancer versus the richest 10%, the poorest decile had a 1.7 times higher risk of cancers with poor prognosis, and the least advantaged were about 2.3 times more likely to be diagnosed at an advanced stage.
- Researchers attribute the gaps to higher tobacco and alcohol exposure, lower participation in organized screening programs, and delays in seeking or receiving diagnosis, with these mechanisms building inequality at multiple stages.
- Policymakers have begun targeted efforts but their effects are unmeasured: Assurance Maladie has stepped up outreach and a pilot lung‑cancer screening program started in mid‑May in five regions for roughly 20,000 high‑risk people, while Drees plans an autumn study on mortality and survival to assess impact.
- The findings mean poorer people in France carry a heavier burden of largely avoidable cancers, so public health responses must combine stronger prevention, tailored screening outreach, and routine evaluation to track whether programs reduce the inequalities described.
