| Mesothelioma is a form of cancer that is almost always caused by exposure to asbestos. In this disease, malignant cells develop in the mesothelium, a protective lining that covers most of the body's internal organs. Its most common site is the pleura (outer lining of the lungs and internal chest wall), but it may also occur in the peritoneum (the lining of the abdominal cavity), the heart,[1] the pericardium (a sac that surrounds the heart) or tunica vaginalis. Most people who develop mesothelioma have worked on jobs where they inhaled asbestos particles, or they have been exposed to asbestos dust and fiber in other ways. Washing the clothes of a family member who worked with asbestos can also put a person at risk for developing mesothelioma.[2] Unlike lung cancer, there is no association between mesothelioma and smoking, but smoking greatly increases risk of other asbestos induced cancer.[3] Compensation via asbestos funds or lawsuits is an important issue in mesothelioma (see asbestos and the law). The symptoms of mesothelioma include shortness of breath due to pleural effusion (fluid between the lung and the chest wall) or chest wall pain, and general symptoms such as weight loss. The diagnosis may be suspected with chest X-ray and CT scan, and is confirmed with a biopsy (tissue sample) and microscopic examination. A thoracoscopy (inserting a tube with a camera into the chest) can be used to take biopsies. It allows the introduction of substances such as talc to obliterate the pleural space (called pleurodesis), which prevents more fluid from accumulating and pressing on the lung. Despite treatment with chemotherapy, radiation therapy or sometimes surgery, the disease carries a poor prognosis. Research about screening tests for the early detection of mesothelioma is ongoing. Mesothelioma Mesothelioma is a rare type of cancer that occurs in the lining of the body's internal organs, a thin layer of cells known as the mesothelium. While very thin, this layer of cells is vitally important to organ function and the health of the inner body structures. There are three recognized types of mesothelioma. Pleural mesothelioma occurs in the pleural lining of the lungs and is the most common form of the disease. Peritoneal mesothelioma occurs within the peritoneum, which lines the abdominal cavity and is the second most common form of the disease. Pericardial mesothelioma is the rarest variety of the disease and occurs in the pericardial lining of the heart. The primary cause of mesothelioma is exposure to asbestos, though other factors, such as smoking may increase the likeliness of the disease in certain individuals. How is Mesothelioma Treated? Mesothelioma is an aggressive cancer but can be managed with chemotherapy, radiation therapy, and surgery. Currently, there is no known cure for asbestos cancer but several mesothelioma treatment regimens have proven to be successful in helping the patient avoid pain and discomfort caused by the disease. Several therapies have emerged in recent years that have extended survival rates to levels previously thought to be impossible. Cancer centers have initiated hundreds of clinical trials in recent years to help mesothelioma patients find a therapy that works for them while still working towards a cure for future patients. Progressive therapies are now being developed through the International Mesothelioma Program under the direction of thoracic specialist Dr. David Sugarbaker. How is Mesothelioma Diagnosed? Malignant mesothelioma can be difficult to diagnose because symptoms of the disease often closely mimic those of less serious conditions. It will often require X-ray and other body scans (CT or MRI) in addition to a biopsy to conclusively diagnose mesothelioma. Nevertheless, those experiencing chronic cough, difficulty swallowing, chest pain, or breathing difficulties should alert their physician immediately. This is particularly true among those with a known asbestos-exposure history. Those with asbestos exposure history should communicate this to their physician even before symptoms appear so that they may be able to alert patients to warning signs of the disease. If detected early enough, patients may be eligible for aggressive treatment options, including surgical resection of the mesothelioma cancer and affected tissue. Oncologists and thoracic specialists will be able to assist the patient in determining the extent of the disease and the best treatment options for that particular patient. Asbestos Exposure Asbestos exposure was common among industrial workers. Among the more common jobsites were those in the shipbuilding industry, such as the Todd Shipyards or Newport News Naval Shipyard. Other jobsites include power plants, chemical manufacturing, or the metal works industry. Those with asbestos history should notify their doctor and learn of possible warning signs of health complications caused by exposure.
