مُساهمةموضوع: I know MATRADE about Mesothelioma   السبت مايو 25, 2013 12:33 pm

Mesothelioma (or, more precisely, malignant mesothelioma) is a rare form of cancer that

develops from cells of the mesothelium, the protective lining that covers many of the internal

organs of the body. Mesothelioma is most commonly caused by exposure to asbestos.[1] The

most common anatomical site for mesothelioma is the pleura (the outer lining of the lungs and

internal chest wall), but it can also arise in the peritoneum (the lining of the abdominal cavity), the pericardium (the sac that surrounds the heart),[2] or the tunica vaginalis (a sac that surrounds the testis).
Most people who develop mesothelioma have worked in jobs where they inhaled or ingested asbestos fibers, or were exposed to airborne asbestos dust and fibers in other ways. It has also been suggested that washing clothes of a family member who worked with asbestos increases their risk for developing mesothelioma.[3] Unlike lung cancer, there seems to be no association between mesothelioma and tobacco smoking, but smoking greatly increases the risk of other asbestos-induced cancers.[4] Some people who were exposed to asbestos have collected damages for asbestos-related disease, including mesothelioma. Compensation via asbestos funds or class action lawsuits is an important issue in law practices regarding mesothelioma (see asbestos and the law).
Signs and symptoms of mesothelioma include shortness of breath due to pleural effusion (fluid between the lung and the chest wall), chest wall pain, and constitutional signs such as unexplained weight loss. The diagnosis may be suspected based on chest X-ray and CT scan findings, but must be confirmed either by examining serous effusion cytology or with a biopsy (removing a sample of the suspicious tissue). A thoracoscopy (inserting a tube with a camera into the chest) can be used to acquire biopsy material, and allows the introduction of substances such as talc to obliterate the pleural space (a procedure called pleurodesis), preventing more fluid from accumulating and pressing on the lung. Despite treatment with chemotherapy, radiation therapy or sometimes surgery, mesothelioma carries a poor prognosis. Research about screening tests for the early detection of mesothelioma is ongoing.
