This rare cancer may develop in the linings around the heart or the testes (pericardium). Asbestos exposure is the primary risk factor for mesothelioma. However, some patients diagnosed with mesothelioma don't have any history of asbestos exposure. Exposure to Asbestos Asbestos, a mineral of natural origin, was previously used for construction and industrial products throughout the world. Workers working in asbestos-related industries were exposed to asbestos on a daily basis. Asbestos fibers can get into the lungs and cause lung disease. This is called asbestosis. Over time, the fibers trapped in the lungs may cause mesothelioma. Asbestos fibers can be inhaled, ingested or even absorbed through the skin. The risk of developing mesothelioma and other asbestos-related illnesses increases when exposed. Most cases of mesothelioma are caused by occupational exposure. Asbestos was employed in many trades, such as construction, insulation, electrical work, automobile maintenance and pipefitting. These occupations are generally heavily populated by males, and as a result mesothelioma cases involving males account for 75-80 percent of all cases reported. However, the gradual elimination of asbestos in the United States and other first-world countries has led to a decrease in exposure on the job. This has resulted in a shift in cases, with non-occupational exposure becoming more prevalent. Non-occupational mesothelioma can occur when asbestos is released from the work environment or in the school or home environment. Exposure to asbestos from the outside can cause it, for example when a family members touches the clothing of an asbestos worker. The people who suffer from this type of exposure may have symptoms like breathlessness or chest pain that is commonly mistaken for lung or heart conditions. Ce
