What is Mesothelioma?

Throughout the past decade, the term "mesothelioma" has become more and more recognizable. Once an obscure disease that meant little to the general public, mention of this disease now conjures up thoughts and pictures of factories and mines strewn with asbestos and the unfortunate workers who were employed in those dangerous places.
Thanks to concerned medical professionals, researchers, and watchdog organizations, we're learning more and more about mesothelioma and how it affects the lives of those who are afflicted. However, there's still far to go as both better treatments and a cure for the disease are sought.
Simply put, mesothelioma which is commonly referred to as asbestos cancer, is an aggressive 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
