Asbestos and Pericardial Mesothelioma

It is well known that asbestos fibers inhaled into the lung are the cause of pleural mesothelioma, which affects the lining of the lungs. However, the means by which asbestos causes pericardial mesothelioma is not well understood, although it is believed that asbestos fibers may travel from the lungs to the heart via the bloodstream.
