Health risks for flight attendants

Sure, the job looks glamorous, but flight attendants have serious health hazards.  They get cancers more than the general population, a lot more.  Flight attendants get more breast cancer and melanoma than other professions.  They also get non-melanoma skin cancers, uterine, gastrointestinal, cervical and thyroid cancers.  Even having multiple children, doesn’t protect a flight attendant from getting breast cancer.  Being a mother is known to be a protective factor against the disease.  What’s causing this?  Is a disruption in the daily sleep cycle to blame?  It’s associated with an increased risk for cancer.  Is it exposure to carcinogenic chemicals or celestial radiation which is also a cancer risk?  What about frequent fliers?  They haven’t been studied, so no one knows.  More research is needed to develop policies to protect aircraft crews.
