Asbestos is a naturally occurring fiber that, when released into the air, can be inhaled or swallowed. Asbestos fibers are so small that they are not visible to the naked eye. Once they are inhaled, asbestos fibers stay in the body and, over the course of decades, lead to the development of asbestos-related diseases like mesothelioma.
Mesothelioma is rare form of cancer caused by asbestos exposure. An estimated 3,000 Americans are diagnosed with mesothelioma each year, and because the disease takes decades to develop, the rate of new diagnoses is still climbing. The peak incidence of mesothelioma is predicted to occur around 2020.
