Breast cancer, the leading cancer diagnosed in women in Auvergne-Rhône-Alpes (33% of cases), shows a slight decrease in its regional incidence between 2017 and 2023. The median age at diagnosis was 64 years. However, significant disparities persist across territories, as highlighted by the breast cancer mortality mapping.
Participation in organized screening, although higher than the national average (51.7% vs. 46.3% in 2023-2024), has decreased by 2.1% compared to the previous period. Participation rates vary considerably from one department to another, ranging from 47.7% in Ardèche to 59.1% in Haute-Loire. Areas such as Cantal, southern Drôme, much of Ardèche, Allier, and Puy-de-Dôme record rates below 48%, posing a major challenge for the new regional roadmap against cancer.
Organized screening, aimed at women aged 50 to 74 and covered 100% by health insurance, allows for early detection of the disease. An annual clinical examination is also recommended from age 25. The examination includes a mammogram with systematic second reading and, if necessary, an ultrasound.
Throughout October 2026, regional stakeholders are mobilizing as part of October Pink. This initiative aligns with the 2026-2030 regional cancer control strategy, focusing on strengthening outreach efforts. Various actions are organized across departments to raise awareness, inform, and facilitate screening access.
The mobilization continues beyond October. The new 2026-2030 roadmap from the ARS Auvergne-Rhône-Alpes aims to reduce territorial inequalities in access to screening and care, and to modernize mammography equipment. Adopting healthy behaviors such as not smoking, limiting alcohol, maintaining a balanced diet, and regular physical activity also helps reduce cancer risk.
