Discuss the occupational and environmental exposure risk factors for mesothelioma.
Exposure to asbestos in certain occupations places patients at risk for mesothelioma. Workers in the field of insulation, fireproofing, plumbing, pipe fitting, plastering, cement production, shipyard construction, boiler making and the automotive brake and clutch industry. Environmental hazards such as joint compound, transite siding, gunnite, roof, floor and ceiling tiles, wall plasters and insulation all pose a threat to patients.
Other rare causes are irradiation of the chest wall, intrapleural thorium dioxide and inhalation of fibrous silicate.
There may be a viral connection to mesothelioma. The Simian Virus 40 (SV40) may be a cofactor in the development of mesothelioma.
Additionally, others living with asbestos workers are at risk of developing this disease. It is thought that exposed workers bring home fibers of asbestos in their clothing and hair which in turn expose their families. Mandatory showering before leaving the workplace is felt to decrease this risk.
