Mesothelioma: What is asbestos?


Asbestos (pronounced play /æsˈbɛstəs/ or /æzˈbɛstəs/) is a set of six naturally occurring silicate minerals used commercially for their desirable physical properties.[1] They all have in common their eponymous, asbestiform habit: long, (1:20) thin fibrous crystals. The inhalation of asbestos fibers can cause serious illnesses, including malignant lung cancermesothelioma (a formerly rare cancer strongly associated with exposure to amphibole asbestos), andasbestosis (a type of pneumoconiosis). Long exposure to high concentrations of asbestos fibers is more likely to cause health problems. This is most common among the miners of asbestos, since they have the longest exposure to it. The European Union has banned all use of asbestos[2] and extraction, manufacture and processing of asbestos products.[3]
Asbestos became increasingly popular among manufacturers and builders in the late 19th century because of its sound absorption, average tensile strength, its resistance to fire, heat, electrical and chemical damage, and affordability. It was used in such applications as electrical insulation for hotplate wiring and in building insulation. When asbestos is used for its resistance to fire or heat, the fibers are often mixed with cement (resulting in fiber cement) or woven into fabric or mats.
Asbestos mining began more than 4,000 years ago, but didn't start large scale until the end of the 19th century. The world's asbestos mining peaked around 1975, when asbestos was being mined in some 25 countries, but is today less than half of what it was in the mid 1970s. For a long time, the world's largest asbestos mine was the Jeffrey mine in the town of Asbestos, Quebec.[4]

Primary malignant Tumor of the pleural is rare. Thirty-three cases (22 males, 11 females, ages 31-68) diffuse pleural mesothelioma is described; all except one has the possibility of exposure to asbestos is crocidolite (blue Cape). The majority of these exposures to asbestos hill located to the West of Kimberley in the Northern Cape province to the West. Tumors are rarely seen elsewhere in South Africa.
