In a groundbreaking decision, a French court has for the first time acknowledged cosmic radiation as a contributing factor to breast cancer in a long-serving flight attendant. Former Air France stewardess Sophie Lainault, now 59 years old, successfully argued that her breast cancer should be recognized as an occupational disease, attributable to work-related conditions. The ruling, handed down in Bayonne, also identified passive smoking and prolonged night work as other carcinogenic hazards associated with her profession. Lainault's case is significant because it establishes breast cancer as an officially recognized occupational risk for flight crews, potentially paving the way for numerous similar claims, according to legal experts. Lainault, who is currently in remission from her cancer, can now retire early and receive full reimbursement for any further treatment through the French health system. The decision comes as a study at Harvard Medical School revealed that flight attendants and pilots have the highest level of radiation-related cancer deaths among over 500 professions, with about 6.9% of deaths among flight attendants and 6.7% among pilots attributed to radiation-related cancers. This rate is higher than for other professions exposed to radiation, such as nuclear technologists, who are routinely exposed to non-cosmic sources but placed 12th on the list. Lainault's lawyer, Elisabeth Leroux, stated that this is the first time a link between breast cancer and certain hazards has been established for an air hostess in France. Air France distanced itself from Lainault's legal case, stating that it had not played a role in it and had not seen the reasoning behind the court's decision. The company emphasized its commitment to the health and safety of its staff, asserting that every employee receives medical support beyond regulatory requirements.
