Malignant mesothelioma is a type of cancer that is usually associated with exposure to asbestos. Indeed, the only known cause of the pathogenesis of mesothelioma is asbestos. This cancer affects areas of the human body, where the mesothelial cells are found.
Pleural mesothelioma includes most cases of malignant mesothelioma. This is the type of malignant mesothelioma that affects the pleura, which is the lining of the lungs. About 70% of cases of pleural mesothelioma to occur. As asbestos fibers are removed from products containing asbestos are inhaled by humans, which then lodge in the lining of the lungs. The human body is capable of physiological waste collection fibers. Over time, these fibers are accumulated way through the mesothelial cells of the pleura. Asbestos fibers are considered as foreign by the body. Therefore, their presence makes the inflammatory reactive process to occur, manifested by pleural thickening, plaque formation, vasculitis, and effusive, even. As the disease progresses, the thickening of the visceral and parietal pleura causes narrowing of the pleural cavity. Meanwhile, the two wings of pleural rub against each other.
These processes are manifested as dyspnea, wheezing and even chest pain or discomfort, fatigue and weight loss in patients. Following mesothelial cell hypertrophy due to the aggressive presence of these fibers would then lead to tumor formation. On average it takes about 40 years against exposure to these fibers to the onset of symptoms.
Peritoneal mesothelioma is approximately 20-25% of all cases of malignant mesothelioma. This type of mesothelioma, which affects the mesothelial cells of the peritoneum. As asbestos fibers in contact with mesothelial cells, which result in changes that induce the cells multiply uncontrollably, and to thicken. Ascites also occurs. Together, these pressure due to the accumulation of abdominal cavity. This pressure also affects other internal organs, and cause them to deteriorate. bowel obstruction often ensues. intestinal veins, thrombosis, and hypoglycemia, and anemia are common symptoms. The lesions may vary from one tumor, a tumor or spread of small calcified nodules.
Pericardial Mesothelioma comprises about 5% of all cases of malignant mesothelioma. This is the least common type of mesothelioma. With pericardial mesothelioma, malignant tumors in the pericardium, the sac of fibrous tissue around the heart. It is speculated that the asbestos fibers as Journey to the heart through the lymphatic system or the cardiovascular patient. As for other cell types of mesothelioma causing asbestos fibers in the pericardium to become thick. This thickening affects the pressure at the chambers of the heart. This causes severe shortness of breath, chest pain, and thrombosis in the veins. Finally gets thickened mesothelial cells to undergo unlimited division and growth, leading to tumor formation. As with other types, the accumulation of pressure of the tumor growth pressure on the heart, which contributes to congestive heart failure.
