Since that time asbestos containing products were used by the construction and building trades the automotive industry and the manufacturing industry. See our page on mesothelioma risk factors. Nevertheless cases of mesothelioma have been documented as the result of lesser exposure affecting family members of workers who came into contact with asbestos and brought it home on their clothing skin or hair or affecting those who lived in close proximity to asbestos manufacturing facilities. Symptoms of asbestos disease usually are not be apparent until decades after exposure. More commonly those who at some point are diagnosed with asbestos disease have worked in jobs where more substantial exposure occurred over longer periods of time. For more than years products containing asbestos remained unregulated and the manufacturers of those products continued to prosper knowing full well that many of the millions of workers who came into contact with their products would ultimately suffer as the result of their actions.
