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 flight attendants and pilots have the highest and second-highest proportions of radiation-related cancer deaths among over 500 U.S. occupations, based on death certificates from 2020 to 2024.
• The research, led by Dr. Vishal Patel, analyzed nearly 13 million deaths and found elevated mortality from cancers linked to cosmic radiation exposure at flight altitudes, including breast, prostate, central nervous system cancers, melanoma, and leukemia in pilots.
• Experts caution that the study shows correlation, not causation, due to missing data on factors like cumulative flight hours, radiation dose, lifestyle, and other exposures, and emphasize that biological plausibility alone does not prove radiation caused the increased cancer deaths.
• Additional occupational factors such as circadian disruption and ultraviolet exposure may contribute to the increased cancer risk, indicating a complex interplay beyond cosmic radiation alone.
• The findings highlight the need for improved monitoring and tracking of cumulative radiation exposure in aircrew careers, but do not currently justify changes to cancer screening guidelines beyond existing recommendations.
