Mesothelioma and Work Exposure Workers who work with asbestos are more at risk of mesothelioma. Construction workers, firefighters or military veterans are especially vulnerable. Mesothelioma mostly affects the lung's lining (pleural mesothelioma) or the abdomen. In rare cases, it can cause damage to the testicles and heart. Consult your GP https://vimeo.com/704982564
