New research is showing that ultra-violet is not the only type of radiation from the sun that can increase the risk of skin cancer. Rates of skin cancer among pilots are twice that of non-pilots, but the glass used in planes blocks most the ultra-violet radiation. Pilots are also exposed to x-rays from the sun during flight. The x-rays that pilots are exposed to in one day of work are equivalent to a chest x-ray. Although getting an x-ray for medical reasons is believed to be safe, researchers believe that the frequent exposer that pilots experience increases their risk for skin cancer.
