What is Pericardial Mesothelioma?

Pericardial mesothelioma is the rarest type of the three forms of mesothelioma. It makes up less than 10% of all mesothelioma patients. Approximately 2,000 new cases of mesothelioma are diagnosed each year, but fewer than 200 of them are pericardial. As with the other mesotheliomas, it is caused by exposure to asbestos.
