Malignant mesothelioma, also known as mesothelioma cancer is a deadly cancer that affects the lining of the lung (pleura), the lining of the abdominal cavity (peritoneum), and the lining of the heart (pericardium). The most familiar type of mesothelioma is pleural mesothelioma, while pericardial mesothelioma and peritoneal mesothelioma are less frequent. Most people who develop mesothelioma have worked on jobs where they inhaled asbestos particles. The main cause of mesothelioma is exposure to asbestos, although other factors such as smoking may result in additional complications.Smoking modern cigarettes does not seem to enlarge the risk of mesothelioma. Simian virus 40 (SV40) may act as a cofactor in the development of mesothelioma. There are five common types of mesothelioma. Four of are malignant cancers, and one is a benign condition. Pleural Mesothelioma type of mesothelioma develops in the lining of the lungs, known as the pleura. It is the most common form of malignant mesothelioma. Peritoneal Mesothelioma form of mesothelioma develops in the lining of the abdominal cavity. Pericardial Mesothelioma form of mesothelioma develops in the lining of the heart, known as the pericardium.

Testicular Mesothelioma is the infrequent type of malignant mesothelioma; to date, there have been less than 100 proof cases. Testicular mesothelioma develops in the tunica vaginalis of the testicles. Benign Mesothelioma benign form of mesothelioma most commonly develops in the pleura. This is the only form of mesothelioma for which full cure and recovery is a probable outcome, though it may be a precursor of future asbestos-related problems. Symptoms of peritoneal mesothelioma include weight loss and abdominal pain and swelling due to a buildup of fluid in the abdomen.

Other symptoms of peritoneal mesothelioma may comprise bowel obstruction, blood clotting irregularities, anemia, and fever. Treatment for mesothelioma depends on the sites of the cancer, the phase of the disease, and the patient’s age and normal health. Surgery is a common treatment for mesothelioma. For cancer of the pleura (pleural mesothelioma), a lung may be removed in an operation called a pneumonectomy. Sometimes part of the diaphragm, the muscle below the lungs that helps with breathing, is also removed. Radiotherapy may be used as part of treatment to try to cure mesothelioma.
