About Mesothelioma

Mesothelioma is a cancer of the cells that make up the lining around the outside of the lungs and inside of the ribs (pleura), or around the abdominal organs (peritoneum).

The mesothelium is a membrane that covers and protects most of the internal organs of the body. It is composed of two layers of cells: One layer immediately surrounds the organ; the other forms a sac around it. The mesothelium produces a lubricating fluid that is released between these layers, allowing moving organs (such as the beating heart and the expanding and contracting lungs) to glide easily against adjacent structures.

The mesothelium has different names, depending on its location in the body. The peritoneum is the mesothelial tissue that covers most of the organs in the abdominal cavity. The pleura is the membrane that surrounds the lungs and lines the wall of the chest cavity. The pericardium covers and protects the heart. The mesothelial tissue surrounding the male internal reproductive organs is called the tunica vaginalis testis. The tunica serosa uteri covers the internal reproductive organs in women. The tissue that lines your lungs, stomach, heart and other organs is called mesothelium. Mesothelioma is cancer of that tissue. It is a rare but serious type of cancer. It usually starts in the lungs, but can also start in the abdomen or other organs. Most people who develop mesothelioma have worked on jobs where they inhaled asbestos particles. It can take a long time - 30 to 50 years - between being around asbestos and getting the disease. Treatment includes surgery, radiation, chemotherapy or all three.

Malignant mesothelioma, also known as mesothelioma cancer is a fatal cancer that affects the lining of the lung (pleura), the lining of the abdominal cavity (peritoneum), and the lining of the heart (pericardium). The most common form of mesothelioma is pleural mesothelioma, although pericardial mesothelioma and peritoneal mesothelioma are less frequent. The main cause of mesothelioma is exposure to asbestos, although other factors such as smoking may result in additional complications.
