Exposure to asbestos is the only known cause of mesothelioma. Asbestos is a crystalline substance that can splinter into tiny chards or dust particles. When these fibers have been breathed in, they travel through the respiratory path and can become lodged within the airways. The smaller fibers are able to travel to the ends of the small air passages and reach the pleura. The tiny bits of mineral cause physical damage to the mesothelial cells. Cancer is the uncontrolled growth of cells that have been altered by a carcinogen. When asbestos fibers irritate the mesothelial cells this seems to trigger the healthy cells to begin reproducing and thus a cancerous situation is created. In addition, the asbestos fibers cause injury to cells that can result in lung cancer and/or asbestosis. Asbestosis is the condition where healthy lung tissue is replaced by scar tissue. If swallowed, these fibers can reach the abdominal cavity where they have a role in causing peritoneal (abdominal) mesothelioma.
Exposure to asbestos most often occurs on the job. Mechanics and construction workers are most likely to be exposed to asbestos-containing materials. Contact with mesothelioma can also be environmental through exposure to products that contain asbestos, such as flooring or ceiling tiles. Exposure can also be a result of household contamination by asbestos fibers brought into the home from the workplace, for example asbestos dust on work clothes.
