18 Dec Pilots and Cabin Crew Fly With Greater Risk of Melanoma
MedicalResearch.com Interview with:
Martina Sanlorenzo, MD
Department of Dermatology
Mount Zion Cancer Research Center
University of California, San Francisco
Medical Research: What is the background for this study?
Dr. Sanlorenzo: We recently performed a meta-analysis and found an increased risk of melanoma in pilots and cabin crew. One of the possible occupational hazards responsible for this risk is UV radiation.
Medical Research: What are the main findings?
Dr. Sanlorenzo: We performed UV measurements in airplane cockpits during flight and we found that windshields blocked UV-B but allowed UV-A transmission. We compared the UV-A dose in airplanes with the UV-A dose in tanning beds, whose use is a known risk factor for melanoma. Pilots flying for 56.6 minutes at 30,000 feet received the same amount of UV-A carcinogenic effective radiation of a 20-minute tanning beds session.
Medical Research: What should clinicians and patients take away from your report?
Dr. Sanlorenzo: Airplanes windshields are not enough to protect pilots from the UV-A radiation, and this could in part explain the increased risk of melanoma in these workers.
Medical Research: What recommendations do you have for future research as a result of this study?
Dr. Sanlorenzo: We recommend further studies including more precise UV measurements in several airplanes to establish occupation-related UV radiation dose limits for pilots. A better UV protection is necessary. We strongly recommend the use of sunscreens and periodical skin check examinations for pilots
