Breast cancer is the leading cause of cancer-related deaths among women in France, with nearly 12,000 deaths annually. While the causes remain complex and often difficult to pinpoint, recent studies have increasingly highlighted the role of night work in elevating risk. A landmark ruling this year offered a significant victory for one nurse, with a court recognizing a direct link between her breast cancer and her work conditions – a decision that could pave the way for similar cases and bolster protections for healthcare workers.
A Nurse’s Challenging Work Conditions
25 Years of Exclusively Night Shifts
The nurse in question worked at the hospital in Martigues for nearly 25 years, almost exclusively on night shifts, averaging around 140 nights per year. This demanding schedule significantly impacted her daily life, disrupting her hormonal balance and biological rhythms. The court emphasized that this prolonged exposure was a contributing factor, especially given the absence of other known risk factors – such as genetic predisposition, hormonal imbalances, or environmental factors – in her case, according to L’Indépendant.
Diagnosis in 2014
She received a breast cancer diagnosis in 2014. Despite undergoing treatment, the nurse faced a dual battle: fighting the disease and seeking recognition of its professional origin. Her initial request for recognition of an occupational disease was denied in 2019, and her employer subsequently refused to acknowledge the connection between her illness and her work in 2021. It wasn’t until this year that the court ruled in her favor.
Court Overturns Hospital’s Denial
The Administrative Court of Marseille determined there was a sufficiently high probability of a direct link between the illness and the nurse’s night work conditions. The court overturned the hospital director’s decision and ordered the hospital to recognize the occupational link. This recognition entitles her to compensation and represents a symbolic win for healthcare workers facing difficult working conditions.
Night Work Recognized as a Risk Factor
Alarming Scientific Studies
As early as 2007, the International Agency for Research on Cancer (IARC), an agency of the World Health Organization, classified night work as “probably carcinogenic.” Research indicates that disruption of circadian rhythms and hormonal functions in women leads to an increased risk of breast cancer. In 2018, the French National Institute of Health and Medical Research (Inserm) found that working nights more than twice a week for over ten years tripled the risk.
Recognition Remains Uncommon
Until recently, very few women have successfully had their breast cancer recognized as an occupational disease. The first favorable decision came in 2023, involving a nurse from the Moselle region exposed to radiation and working nights for 28 years. The 2026 ruling in Marseille is therefore a significant step forward that could encourage other healthcare workers to pursue similar claims. This case highlights the need for a clearer legal framework for professions with atypical schedules, particularly in the healthcare sector.
A Public Health Issue
Breast cancer remains the most deadly cancer among women in France. Recognizing the role of night work in its development raises a major public health concern. It prompts questions about the working conditions of healthcare professionals, who are often subjected to demanding night schedules, and the need to strengthen preventative measures. This judicial decision could encourage public authorities to better regulate night work and develop appropriate protective measures.
