What are the main causes of mesothelioma?
Mesothelioma is most predominantly caused by asbestos exposure. Asbestos fibers that are inhaled through the mouth and nose may eventually become embedded in the lining of the lungs, causing damage and resulting in mesothelioma lung cancer or asbestosis (scar tissue formation in the lungs). It has also been found that swallowing asbestos fibers could contribute to a form of mesothelioma originating in the abdomen called peritoneal mesothelioma.
Mesothelioma cancer generally results from occupational exposure but there are instances of environmental exposure to asbestos that can cause mesothelioma disease. Oftentimes second hand exposure of a family member to an asbestos workers dirty work clothes can result in that family member having a mesothelioma diagnosis.
Asbestos insulation workers appear to have the highest death rate. One study reports that almost six percent of asbestos workers fall victim to mesothelioma or experience mesothelioma symptoms and asbestos insulation workers are over 300 times more likely to die from mesothelioma than the general public.
