Greater risk of certain cancer deaths linked to 2 of "best jobs" in America

Key Points:

• A study published in JAMA Internal Medicine found that U.S. flight attendants and pilots have the highest and second-highest proportions of radiation-related cancer deaths among over 500 occupations, based on analysis of nearly 13 million death certificates from 2020 to 2024.
• The research highlighted increased deaths from cancers linked to radiation, such as breast, prostate, central nervous system cancers, melanoma, and leukemia in pilots, attributing this to cosmic radiation exposure at commercial flight altitudes.
• Experts caution that the study shows correlation but does not prove causation, noting the lack of data on factors like cumulative flight hours, radiation dose measurements, and lifestyle habits, which limits definitive conclusions.
• Other contributing factors such as circadian disruption and ultraviolet exposure may also play roles in the elevated cancer risk observed among flight crews, indicating a complex interplay beyond radiation alone.
• The findings underscore the need for improved monitoring of occupational radiation exposure and cumulative dose tracking over careers, rather than immediate changes to cancer screening protocols, to better understand and manage health risks for aircrew members.
