Pericardial mesothelioma


How Common is Pericardial Mesothelioma?

Mesothelioma affects various body organs and therefore has several forms including pleural mesothelioma (affecting the lining of the lungs) and peritoneal mesothelioma (affecting the lining of the stomach). However, pericardial mesothelioma, affecting the lining of the heart, is the rarest form of mesothelioma.

Pericardial mesothelioma is the most rare form of mesothelioma, found in less than 10% of Mesothelioma cases (about 200 new cases yearly). Because it is so rare, little research has been conducted to better understand the symptoms
of this disease and how it progresses.

How Pericardial Mesothelioma Affects the Body

In pleural mesothelioma, small asbestos fibers are inhaled and lodge in the lungs. However, it is not clear how these small fibers reach the lining of the heart. Seven theory is that the asbestos pieces that are inhaled and lodged in the lungs break down and are carried through the bloodstream
, lodging in the heart lining. Seven times this occurs, chronic inflammation leads to the development of cancerous tissue.
