Thyroid Cancer 101: Flight Attendants at Risk?
Dr. Guttler’s comments:
1. Thyroid cancers were all seen at a higher rate in flight attendants.
2. 80 % are women. Thyroid cancer is more common in females.
3. Carcinogens like pesticides, fire retardants, jet fuel and other chemicals more frequently than the general population.
4. They are also exposed to higher levels of cosmic ionizing radiation.
5. Frequent flyers may also be at risk.
6.In Europe, flight attendants’ exposure to cosmic ionizing radiation is monitored and limited more by law.
7. We have no similar protection for our FA’s.

Researchers don’t exactly know why this is the case, but they have some guesses.
A flight attendant’s life may look glamorous, but the job comes with health hazards that go beyond managing surly passengers. As a group, they get certain cancers more than the general population, according to a new study.
Disruptions in circadian rhythm — a person’s daily sleep-wake cycle — are linked to an increased cancer risk, studies have shown.
Eighty percent of the flight attendants in the study were women, as would be expected, the authors said, in a “feminized” occupation.
The research does not answer why flight attendants report higher cancer numbers, but the authors have some ideas, based on earlier research. Flight attendants are often exposed to possible or probable carcinogens like pesticides, fire retardants, jet fuel and other chemicals more frequently than the general population. They are also exposed to higher levels of cosmic ionizing radiation; the World Health Organization says this is a cancer risk.
If you fly a lot, should you worry about your own cancer risk? Mordukhovich said there isn’t a lot of research on frequent fliers, although logic suggests that they face similar exposures. Independently, NASA scientists have studied high-altitude radiation to help improve monitoring for aviation industry crew and passengers.
Steve Fiering, a professor of microbiology and immunology at the Geisel School of Medicine at Dartmouth, said it’s hard to argue with the idea behind the recent study.
Fiering, who was not involved in the study but conducts research on flight attendants, said he found the higher rates of melanoma and non-melanoma skin cancer among women in the study “striking” — “especially to see a close to four-fold increase in non-melanoma skin cancer; that is substantial,” he said.
Mordukhovich said she and her colleagues were motivated to study flight attendants because there are gaps in the research on them, and that could mean gaps in the policies meant to protect them on the job, at least in the United States.
In Europe, flight attendants’ exposure to cosmic ionizing radiation is monitored and limited more by law. There are no official dose limits for American aircrew. In fact, it wasn’t until 2014 that US flight attendants got protections from the Occupational Safety and Health Administration like other American workers, but even today, those protections are limited, Mordukhovich said.
“Our goal with this is to do the science and provide more evidence for policy-makers about this profession’s health,” Mordukhovich said. “We hope this helps.”
