What is Mesothelioma

Mesothelioma is a rare form of cancer in which malignant (cancerous) cells are found in the sac lining the chest or abdomen. Exposure to airborne asbestos particles increases the risk of developing malignant mesothelioma.
The word Mesothelioma (like other cancer names) is derived from mesothelium, a membrane that covers and protects most internal organs of the body. Mesothelium is composed of two layers of cells, one layer surrounds the organ and the second layer forms a sac around it. Lubricating fluid is produced by the Mesothelium and is released between the layers which help moving organs to flow easily against adjacent structures. Organs such as the heart, lungs and stomach that expand and contract rely on this fluid.
