Environmental exposures

Incidence of mesothelioma had been found to be higher in populations living near naturally occurring asbestos. For example, in Cappadocia, Turkey, an unprecedented mesothelioma epidemic caused 50% of all deaths in three small villages. Initially, this was attributed to erionite, however, recently, it has been shown that erionite causes mesothelioma mostly in families with a genetic predisposition.
