What is the cause of pericardial mesothelioma?
Asbestos is the main cause of pericardial mesothelioma. When exposed to asbestos without sufficient protection, dust and fibres from the asbestos are inhaled and become lodged in the lungs. From here they can either pass into the lymphatic system and get transported to the lining of the heart or the fibres can just pass through to the heart over time.
