Exposure To Volcanic Mineral Associated with Increased Mesothelioma

Mesothelioma and Minerals

High exposure to a fibrous volcanic mineral called erionite was associated with a high incidence of a type of cancer called mesothelioma, according to a study in the March 15 issue of the Journal of the National Cancer Institute.

Many cases of environment-related mesothelioma have been reported in the Cappadocia region or Anatolian plateau of Turkey. Blocks of erionite from volcanic tuff have been used in construction, and storage rooms for produce have been cut in the tuff. Past reports have suggested that erionite exposure may increase the risk of mesothelioma, and studies have shown that erionite is associated with a higher risk of cancer development in animals than any other fiber previously tested.
