Pericardial Mesothelioma Causes

Further symptoms may arise due to compression of coronary arteries and local spread into the surrounding great vessels.

Pericardial mesothelioma causes. The causal relationship between asbestos exposure and this type of mesothelioma is not fully understood. Dyspnea or difficulty breathing. It is one of the rarest forms of mesothelioma accounting for 1 2 of all diagnoses. Common clinical manifestations of pericardial mesothelioma are constrictive pericarditis pericardial effusion cardiac tamponade and heart failure caused by myocardial infiltration.

Researchers confirm the pleural and peritoneal types are primarily caused by exposure to asbestos yet the causes of the pericardial type are less definitive. The onset of symptoms is usually insidious. The primary cause of pericardial mesothelioma remains a mystery. Some researchers argue that the most common cause of pericardial mesothelioma is through metastasis with several studies stating that primary pericardial mesothelioma is extremely rare and may even be benign.

Pericardial mesothelioma is extremely rare. The only known cause of pericardial mesothelioma is exposure to asbestos a naturally occurring mineral that has been used in common household and industrial building products for decades. Pericardial thickening and effusions prevent the heart from expanded and contracting normally. The buildup of excess fluid in the pericardial sac pericardial effusion and thickening of the pericardium cause many of the symptoms of this disease.

Asbestos is a mineral that s found naturally in the environment. While pleural and peritoneal mesotheliomas are strongly associated with asbestos exposure the link is weaker with pericardial mesothelioma. Having a family history of this cancer and being exposed to asbestos over a long period of time are the two strongest risk factors. Most mesotheliomas are thought to be related to asbestos exposure.

Like pleural mesothelioma causes are thought to include exposure to asbestos. This results in tumors in the pericardium the protective lining around the heart. Asbestos fibers are strong and resistant to heat making them useful in a wide variety of applications such as in insulation brakes shingles flooring and many other products. There may be a component of environmental or genetic factors but pericardial mesothelioma is simply too rare to be certain.

Symptoms caused by pericardial mesothelioma include. Though some associations have been noted the cause of these tumors is usually unknown. Pericardial mesothelioma pericardial mesothelioma is an extremely rare form of asbestos cancer that develops in the pericardium a membrane that lines the heart. Some patients have extended their life expectancy more than a year with the right treatment.
