Exposure to asbestos is the primary cause of mesothelioma.
Asbestos is a naturally occurring mineral or group of minerals. It is a “mined” mineral that takes on the form of natural fibers. These fibers a capable of floating in air and can lodge into the lungs, causing infection and other damage to the cells.
Asbestos is also found in products such as old plastics, textiles, electrical switchboards, caulking/patching tape, brake linings, paper products, crayons containing talc, and heavy industrial sealants. There is a widespread use of asbestos in manufacturing because heat and chemicals do not affect asbestos and it is not a conductor of electricity. Asbestos is often added to cement and plastic to increase its durability. It is also used in some products for fire proofing and sound absorption.
Asbestos is a dust-like fiber that clings to clothing, skin, fingernails, and hair. As a result of this, workers exposed to asbestos also run the risk of exposing other people who are in close contact.
