Understanding Mesothelioma

Friday, March 18, 2011
Mesothelioma is a form of cancer of the membranes that surround the lungs and line the chest cavity. There are a number causes of mesothelioma. The main cause is the inhalation of asbestos fibers. Although the risk of developing mesothelioma rises with the amount of asbestos exposure, it is clear that genetic factors also play a role in determining who develops the disease.

Symptoms of mesothelioma do not typically arise until the disease has reached the late stages. Symptoms of mesothelioma may not appear until 30 to 50 years after exposure to asbestos. Symptoms of mesothelioma in the lung may include shortness of breath and vague chest pain that may radiate to the shoulders or upper abdomen. Other symptoms may include loss of appetite, fatigue, hoarseness, weakness, and weight loss.

The median mesothelioma life expectancy after diagnosis is about 14 months; in some instances it is much longer, presumably reflecting disease that was ascertained at an earlier stage.
