Mesothelioma is a disease in which malignant cancer cells are found in
mesothelium. The mesothelium is a protective sac that covers most of
bodies major organs.The mesothelium is made up of two layers of cells:
One layer immediately surrounds
organ; The other layer forms a sac around it.
The mesothelium produces a lubricating fluid that is released between these layers. The purpose of this lubricating fluid is to allow moving organs, such as
heart and lungs to glide against adjacent structures.
Malignant mesothelioma is a disease in which cancerous cells in
mesothelium grow to an abnormal size and divide uncontrollably. During this process these malignant mesothelioma cells will invade and contaminate nearby organs and tissues.
Cases of malignant mesothelioma have increased over
last 20 years, but despite this, mesothelioma is still a comparatively rare form of cancer with about 2000 new cases a year being diagnosed in
United States.
Malignant mesothelioma occurs much more in men than in women and you're much more likely to contract it when you're old than young.
