Pleural Mesothelioma

Mesothelioma is a form of cancer that is caused almost exclusively by exposure to asbestos. It is still a very uncommon disease; however, new cases are being diagnosed at an increasing pace. This is due to the fact that the time between asbestos exposure and development of mesothelioma can range from 15 to 50 years. Asbestos, a naturally occurring bundle of minerals, was primarily used between the 1940s and 1980s for insulation in manufacturing and building products.

When asbestos is breathed into the lungs, it can attach itself to the tissues inside and remain for years, causing the development of mesothelioma. Mesothelioma involves the linings of the lungs, unlike typical lung cancer that is inside of the lungs. This lining is called the mesothelium, and surrounds all major organs for protective purposes. When mesothelioma develops, cells begin to grow abnormally and at a rapid pace. Mesothelioma of the lungs is called pleural mesothelioma.

There are several symptoms that can warn of developing mesothelioma, although, like other cancers, it is impossible to know it will occur before it is actually present. Unfortunately, the symptoms of pleural mesothelioma can mimic that of typical viral pneumonia. This can lead to misdiagnosis for some period of time. If you are experiencing any of the following symptoms and are aware of asbestos exposure, it is imperative that you seek medical advice regarding mesothelioma as soon as possible.

• Ongoing shortness of breath (also called dyspnea)
• Persistent cough, wheezing, and/or hoarseness
• Chest pain
• Unexplained weight loss
• Lower back pain
• Difficulty swallowing

Pleural mesothelioma also commonly causes pleural effusion, which is the accumulation of fluid between the linings of the lung and the chest wall. A physician may need to drain this fluid for symptomatic relief, as well as for diagnosis. Other ways diagnosis is obtained is through careful review of past medical and social history, and through imaging studies such as a chest x-ray, an MRI, or a CAT scan. However, the only way doctors are able to give a definitive diagnosis of mesothelioma is through a biopsy of the suspect tissues.

Treatment of pleural mesothelioma usually consists of surgery, radiation therapy, and/or chemotherapy. Right now, the life expectancy of those who are diagnosed with pleural mesothelioma is between 8 and 12 months, depending on how far the disease has progressed. Studies and clinical research are being conducted, though, and more effective therapies are in the process of being developed.
