Types of Mesothelioma

Pleural Mesothelioma

Pleural mesothelioma represents about 75% of all mesotheliomas. The disease can grow quickly and enlarge the pleural space, causing it to fill with fluid. This fluid leads to the discomfort or pain associated with first detection of the disease. It is thought that pleural mesothelioma is caused by the inhaling of fibrous materials, including asbestos. These fibers become lodged in the pleura and, over time, cause damage that can lead to cancer. Learn more about pleural mesothelioma.

Pericardial Mesothelioma

The rarest form of mesothelioma is that which affects the linings of the heart cavity, called the pericardium. Less than 10% of all mesothelioma cases are related to the heart. As in the lung, the rapid growth of the cancerous tumors can cause expansion of the tissue and accumulation of fluid. The fluid can interfere with the functioning of the heart and cause chest pain. Mesothelioma cases are known to be caused by exposure to asbestos; but it is completely unknown how the asbestos fibers enter the tissue layers surrounding the heart.

Peritoneal Mesothelioma

Mesothelioma of the abdomen is called peritoneal mesothelioma. The serous membrane surrounding the abdomen is known as the peritoneum. This disease accounts for approximately 10% to 20% of mesothelioma cases. In addition, a rare form of peritoneal mesothelioma affects the male testicles. The covering layer of the scrotum is actually an outpouching of the peritoneum. Peritoneal mesothelioma is due to the ingestion of fibrous materials, including asbestos.
