As its name suggests, asbestos cancers are caused by the inhalation or ingestion of asbestos. When these toxic fibers enter the body, they can cause genetic changes in healthy mesothelial cells. Over time, healthy mesothelial cells die and tumors grow in their place. Asbestos exposure is practically the only cause and risk factor for mesothelioma, while lung cancer can be caused by smoking cigarettes or exposure to radon.
Although smoking exacerbates any potential symptoms that asbestos-related diseases may display, it does not increase your risk of developing mesothelioma if you’ve been exposed to asbestos. Conversely, smoking combined with asbestos exposure does greatly increase the risk of developing lung cancer. Other factors that may affect a person’s overall health and risk of developing cancer following asbestos exposure may include a lifestyle low in exercise, high in stress and poor dietary choices.
