Causes of Mesothelioma
Asbestos fibers are the primary cause of mesothelioma. They are microscopic, cannot be seen with the human eye and when they are ingested or inhaled go unnoticed. Asbestos fibers are given off by asbestos products that have deteriorated and become “friable,” which means that they easily crumble – at which point the fibers can become airborne in dust clouds. In thousands of industrial sites and repair shops where asbestos insulation or other products were used, workers inhaled asbestos fibers on the job – sometimes on a daily basis.
When asbestos fibers are inhaled or ingested, the human body cannot excrete them through any natural means such as coughing, sneezing or any other physiological function. The fibers remain within the body, eventually embedding themselves in tissue; in most cases that tissue is the mesothelium. Asbestos fibers remain in the body forever; eventually they begin to cause problems with the mesothelium tissue. They can cause abnormal cells to develop and those cells begin to reproduce uncontrollably. Often they are cancerous cells, which begin to form the diffuse tumors that characterize most cases of mesothelioma.
