A new study published in JAMA Internal Medicine reveals that flight attendants and pilots face significantly higher risks of dying from radiation-related cancers compared to the general population. Researchers analyzed national death certificate data from over 12 million individuals, identifying occupations with elevated cancer mortality rates. Flight attendants had a 50% higher risk, while pilots showed a 36% increase, for cancers linked to radiation exposure such as leukemia, lymphoma, and thyroid cancer. The study highlights that cosmic radiation at high altitudes contributes to this risk, though limitations include unknown exposure levels and potential misclassification of occupations. Experts emphasize the need for better monitoring and health protocols for aviation crews, suggesting regular skin exams and early cancer screenings. The Federal Aviation Administration acknowledges radiation exposure but lacks federal dose limits or mandatory monitoring. Union leaders stress the importance of addressing this known risk, calling for improved education and accountability in aviation safety.
