Who is most likely to get pleural mesothelioma?

Asbestos exposure. Most cases (70-80%) of mesothelioma happen in persons with environmental exposure to asbestos. Radiation exposure is another risk factor and smoking increases the risks. Thus, a person with a history of work-exposure to asbestos is at highest-risk of developing mesothelioma.
Asbestos-exposure. Those exposed to asbestos are most prone to getting malignant mesothelioma, either directly through work or indirectly through close contact with clothes of those exposed at work, such as pipe-fitters, boilermakers, brake repair. Some also have suggested that exposure to the earliest polio vaccines, which may have been contaminated with another virus, sv40, may be prone to developing mesothelioma.
