Malignant mesothelioma is a type of cancer that is more often associated with exposure to asbestos. In fact, the only case known to the pathogenesis of malignant mesothelioma is asbestos. This cancer affects areas of the body where cells mésotheliales.
Pleural mesothelioma includes the majority of cases of malignant mesothelioma. It is the type of malignant mesothelioma that affects the pleura, which is the lining of the lungs. About 70% of all malignant mesothelioma cases occur in the pleura. As asbestos fibres which are dismissed off the coast of asbestos-containing products get inhaled by humans, these then get lodged in the wall of the lungs. The human body has no ability to physiologically eliminate these fibres. Over time, these fibres accumulated will find their way in the cells pleura mésotheliales. These asbestos fibres are considered as foreign bodies by the organization. Thus, their presence causes reactive inflammatory processes to occur, manifested by a pleural thickening, plate, Vasculitis and same panegyrics formations. As the disease progresses, the thickening of the parietal and visceral pleura causes the narrowing of the pleural cavity. Over time, the two leaves of the pleura rubbing against each other. This process occurs by dyspnea, trades and pain in the chest same or malaise, fatigue, and loss of weight in the patient. Continuous enlargement of cells mesothelial due to violent of these fibres will result the formation of tumors. On average, it takes approximately 40 years of exposure to these fibers to the manifestation of symptoms.
Peritoneal Mesothelioma includes approximately 20 to 25% of all cases of malignant mesothelioma. It is the type of mesothelioma that affects the peritoneum mésotheliales cells. As asbestos fibres come into contact with mésotheliales cells, they make changes that cause the cells to multiply without restraint and thicken. Ascites also occurs. Together, these cause the pressure in the abdominal cavity accumulation. This pressure affects the other internal organs and encourages them to deteriorate. It follows a bowel obstruction often. Thrombosis of intestinal veins and hypoglycemia and anemia are the initial symptoms. Lesions vary unique tumor, small diffuse tumors or calcified nodules.
Pericardial mesothelioma includes about 5% of all cases of malignant mesothelioma. It is the less common type of mesothelioma. With pericardial mesothelioma, malignant tumours are found on the pericardium, the sac of fibrous tissue surrounding the heart. It is assumed that the manner in which the journey asbestos fibres is through the lymphatic system or cardiovascular patient. As with other types of mesothelioma, asbestos fibers cause the cells of the pericardium to thicken. This thickening affects the pressure on the Chambers of the heart. This results in turn severe shortness of breath, chest pain, and thrombosis in the veins. Over time, the thickening also causes mésotheliales cells undergo without restriction of division and growth, leading to the formation of tumors. As with other types, the accumulation of excessive pressure of the tumor growth puts pressure on the heart that contribute to heart failure.
