What is Mesothelioma Cancer?

Mesothelioma is a rare form of cancer that develops around the protective lining of the organs, the mesothelium. The cause of mesothelioma cancer is generally attributed to prolonged asbestos exposure. Most people that develop mesothelioma cancer have experience working in areas where they were exposed to asbestos on the job site. Such job sites may include shipyards, factories and even home renovation.

Pleural Mesothelioma: The most common form of mesothelioma cancer is pleural mesothelioma. This type of mesothelioma develops in the lining of the lungs, known as the pleura, but may also develop in the peritoneum (lining of the abdominal cavity) or the pericardium (sac that surrounds the heart). It is the most common form of malignant mesothelioma, with around 75 percent of cases being pleural in origin.

Peritoneal Mesothelioma: Comprising approximately 20 percent of mesothelioma cases, this form of mesothelioma develops in the lining of the abdominal cavity, known as the peritoneal membrane.

Pericardial Mesothelioma: This form of mesothelioma develops in the lining of the heart, known as the pericardium. Approximately 5 percent of all mesothelioma cases are pericardial.

Testicular Mesothelioma: Testicular mesothelioma develops in the tunica vaginalis of the testicles and is the rarest form of the cancer.
