Malignant mesothelioma is an aggressive but rare malignancy that principally affects the pleura and peritoneum. The pleura and peritoneum are lining that cover the lung (pleura) and the abdominal cavity (peritoneum). In recent years, a steady proportional increase in pleural tumors has been matched by a proportional decrease in peritoneal tumors.[1]

Roughly 80% of cases are believed to derive from occupational or paraoccupational exposure to primary asbestos fiber types (thus the high mesothelioma asbestos claim numbers); namely, crocidolite, amosite, and chrysotile in a ratio of 500:100:1, respectively, and, less commonly, by exposure to tremolite (which has little commercial value and is therefore mined in limited quantities). These are the cases most associated with mesothelioma lawsuits and claims across the country requiring the assistance of a mesothelioma lawyer. According to recent mesothelioma statistics from Great Britain's Health and Safety Executive's Epidemiology and Medical Statistics Unit, risk appears to be highest among workers associated with the following broad areas of asbestos use: shipbuilding, railway carriage and locomotive building, and installation/maintenance of insulation materials in buildings or industrial plants.

The remaining 20% of cases have no clear-cut occupational cause and are believed to be related to etiologic factors, including contact with nonindustrial fibers such as erionite and exposure to simian virus 40 (SV40), a DNA tumor virus affecting Asian macaques that contaminated poliovirus vaccine stocks used in the late 1950s/early 1960s.
