The most common cause of mesothelioma is exposure to asbestos. In nearly all cases, those infected have been either directly or indirectly exposed to this mineral substance. Asbestos was commonly used as an insulation material, due to its strength and resistance to heat and fire. It was also used in ship-building and in common household appliances.

It wasn't until the 1960s that doctors first noticed the health risks posed by asbestos. At that time, they saw a flurry of patients with similar occupational backgrounds reporting the same set of symptoms. As a result, physicians were able to prove the link between asbestos and mesothelioma. 

The individuals most likely to have come into contact with asbestos include construction workers, factory workers, miners, shipbuilders, plumbers and electricians. In addition to workers who had direct contact with asbestos, the family members of these individuals were often indirectly exposed as well.

The danger posed by asbestos is due to the fact that it is made up of hundreds of tiny fibers.  When the material is disturbed, these fine fibers are released and enter the lungs of those nearby. Because they are so small, the fibers get stuck in the lungs and cannot be coughed out or released via normal breathing. The body's immune system unsuccessfully attempts to destroy the fibers, which results in inflammation of the lung tissue.

Asbestos fibers may also be swallowed, at which point they get stuck in the digestive tract. This results in the less common peritoneal form of mesothelioma, which affects the lining of the abdomen. The rarest form of the condition is the pericardial type, which affects the lining of the heart.

As a result of medical research and public outcry, the use of asbestos was regulated by the Clean Air Act of 1970. In 1989, the United States Environmental Protection Agency issued an outright ban of the material. Since that time, the ban has overturned, and certain products containing trace amounts of asbestos are still allowed under United States law.
