Asbestosis is a process of diffuse interstitial fibrosis of the lung due to exposure to asbestos dust. Asbestos is the name given to a group of naturally occurring minerals that are resistant to heat and corrosion; these include mineral fibers such as chrysotile, amosite, and crocidolite, among others. Chrysotile is by far the most common type of asbestos fiber produced in the world, and it accounts for virtually all commercial use of asbestos in the United States.
