About the Disease

Simply put, mesothelioma is an aggressive form of cancer caused primarily by the inhalation of dangerous asbestos fibers. The disease attacks the mesothelium, a protective, two-layered membrane that covers the internal organs of the body including the lungs, heart and abdominal organs. Between these layers, the cells produce fluid, which allows easy movement of the heart and lungs within the chest cavity. The layer that covers the lungs is called the pleura, and the layer that covers the heart is called the pericardium. The peritoneum lines the abdominal cavity. Mesothelium also lines the male and female reproductive organs. Mesothelioma can affect any of these cells, but is usually seen in the pleural or peritoneal mesothelium. The most commonly diagnosed form of this cancer is pleural mesothelioma.

Mesothelioma takes anywhere from 20 to 50 years to develop, which is why older individuals are usually the victims. However, recent cases involving September 11th World Trade Center first responders and clean-up crews show that high concentrations of asbestos can cause the disease to develop much more rapidly. A few WTC workers have already died of the disease.
