Can Mesothelioma Develop in the Heart?

Mesothelioma can develop in the pericardium, which is known as pericardial mesothelioma. This particular form of mesothelioma is very rare, with research indicating that it comprises from one to six percent of total mesothelioma diagnosis. Pericardial mesothelioma accounts for approximately half of all pericardial tumors. Pericardial tumors tend to be diffuse, which means they are not localized and likely to cover most of the heart.
