What is Mesothelioma?
Pleural pleural mesothelioma is a primary tumor, there are localized (mostly benign) and diffuse (all malignant) of the sub. One type of diffuse malignant mesothelioma is a chest tumor one of the worst prognosis. The first symptom to chest pain, shortness of breath and coughing the most common. To have fever, sweating or joint pain mainly v. symptoms. About more than half of a large number of pleural effusion of patients with severe shortness of breath. A large number of those without pleural effusion often more severe chest pain, weight loss common. Ordinary X-ray revealed pleural effusion, while lung tumor tissue was wrapped, and so on, have advanced cases of pericardial effusion caused by the heart shadow and the expansion of soft tissue damage, such as video and ribs. Suspicious for malignant pleural mesothelioma patients, CT examination of the most useful. Pleural effusion cytology also contribute to the diagnosis. Conventional laboratory tests, some patients may have a number of platelets, serum carcinoembryonic antigen (CEA), and so increased. For routine inspection diagnosis is not entirely clear, can be used to do thoracoscopic pleural biopsy. In general most patients can not obtain a diagnosis.'s Treatment of malignant pleural mesothelioma, is still no effective cure method. Treatment, have surgery, chemotherapy and radiation treatment, the tumor is generally believed that the relatively limited period I patients, so that solution to the problem of pleural pneumonectomy. For Ⅱ, Ⅲ, Ⅳ phase patients, radical surgery has no meaning, only the implementation of palliative operation in the incidence of the majority of patients between the ages of 40-70, more men than women. The cause of mesothelioma is a major cause of mesothelioma patients of asbestos exposure. About 70 - 80% of patients with the diagnosis of mesothelioma in the history of asbestos exposure at work. However, there are some mesothelioma patients and there is no record of asbestos exposure. The asbestos fibers can be a large number of dispersed into the air and minerals. Asbestos was widely used in many industrial products, including cement, brake linings, roof shingles, textiles and insulation materials. If tiny asbestos particles floating in the air, especially in the manufacturing process, they will be inhaled and cause serious health problems. In addition to mesothelioma, the asbestos exposure of the increase in lung cancer, asbestosis (noncancerous, chronic lung disease) risk, and other cancers, such as the throat and kidney cancer. The combination of smoking and asbestos greatly increase the risk of air passage of the risk of disease. Mesothelioma asbestos exposure mesothelioma manufacturers in the early 1970s before the understanding of asbestos exposure can lead to mesothelioma cancer risk, but they will this information as trade secrets with tighter control. On first exposure to asbestos is reported in the mid-60. Even today, asbestos manufacturers still try to hide the fact that the risk of long asbestos. Long-term human exposure to asbestos in the environment caused by inhaling asbestos and mesothelioma risk to increase dramatically, but a recent study found that even very short-term exposure to asbestos can cause the disease. Typically, mesothelioma need 20-40 years before symptoms show, people usually aged between 50-70 who were diagnosed until the disease. Although the reported rate of increase in the past 20 years, mesothelioma is still relatively rare cancer. The United States each year there are about 2,000 new mesothelioma was diagnosed cases.
