What is Pericardial Mesothelioma?
Pericardial mesothelioma is basically mesothelioma of the heart wall. It develops in the pericardium, a membrane made up of mesothelial cells that surrounds the heart and provides protection and support to this organ. The membrane is made of two layers: an outer layer that is called the parietal and an inner layer called visceral. The parietal layer is part of a larger membrane that lines the chest cavity, and the visceral layer is the pericardial membrane that lines the heart. Diseases associated with asbestos may take from ten to forty years before symptoms of the disease appear. The symptoms of pericardial mesothelioma are: shortness of breath, chest pain, palpitations of the heart and bad cough.
Common Causes of Pericardial Mesothelioma
It is common knowledge that pleural mesothelioma, which starts in the lining of the lungs, is caused by breathing of asbestos fibers. However, the way in which asbestos starts the development of pericardial mesothelioma is not known at this time. Some researchers think that inhaled asbestos fibers are introduced through the bloodstream from the lungs to the heart, although there is no sure evidence to support this idea. Asbestos fibers somehow get into and become lodged in the pericardial membranes that surround the heart. When this happens, the body begins to experiences problems with getting rid of the asbestos fibers and they can remain trapped in the membranes. After some time, maybe over two decades or more, the trapped asbestos fibers cause the cells of the pericardium to deform that may result in the cancer.
