Pericardial Mesothelioma Causes

This results in tumors in the pericardium the protective lining around the heart.

Pericardial mesothelioma causes. It is one of the rarest forms of mesothelioma accounting for 1 2 of all diagnoses. Though some associations have been noted the cause of these tumors is usually unknown. 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. 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.

The primary cause of pericardial mesothelioma remains a mystery. Most mesotheliomas are thought to be related to asbestos exposure. The onset of symptoms is usually insidious. This is particularly true when the tumors begin in young people.

Pericardial thickening and effusions prevent the heart from expanded and contracting normally. Prognosis is extremely poor with most cases being diagnosed only after an autopsy. It is caused by asbestos fibers lodged in the lining of the heart. Pericardial mesothelioma is extremely rare.

Symptoms caused by pericardial mesothelioma include. The causal relationship between asbestos exposure and this type of mesothelioma is not fully understood. Dyspnea or difficulty breathing. Some patients have extended their life expectancy more than a year with the right treatment.

There may be a component of environmental or genetic factors but pericardial mesothelioma is simply too rare to be certain. 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. Researchers confirm the pleural and peritoneal types are primarily caused by exposure to asbestos yet the causes of the pericardial type are less definitive. While pleural and peritoneal mesotheliomas are strongly associated with asbestos exposure the link is weaker with pericardial mesothelioma.

Common clinical manifestations of pericardial mesothelioma are constrictive pericarditis pericardial effusion cardiac tamponade and heart failure caused by myocardial infiltration. Pericardial mesothelioma pericardial mesothelioma is an extremely rare form of asbestos cancer that develops in the pericardium a membrane that lines the heart. Further symptoms may arise due to compression of coronary arteries and local spread into the surrounding great vessels. Asbestos is a mineral that s found naturally in the environment.
