Mesothelium covers the external surfaces of the heart and lung. It also covers the inner surface of the chest wall and the inner surface of the sac that surrounds the heart called pericardium. In the lungs the mesothelium is called pleura, in the heart it is called pericardium, and in the abdominal cavity it takes the name of peritoneum.
Its primary role is to protect these organs by producing a lubricating fluid that allows for movement. While mesothelioma can affect any of the mesothelial tissue in the body, it is most commonly seen in the pleural or peritoneal mesothelium. Sadly, many patients are not diagnosed with mesothelioma until symptoms are present, and symptoms are not usually present until the cancer is in its advanced stages.
To understand this a little better, let's clarify that 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. It (cancer of the mesothelium) is a disease in the cells of the mesothelium, which become abnormal and divide without any control and order. They can invade and damage nearby tissues and organs. Mesothelioma (cancer of the mesothelium) occurs when the cells of the mesothelium become abnormal and divide without control or order.
Nearby tissues and organ can be affected and the cancer cells can also metastasize (spread) from their original site to other parts of the body.
So what is Asbestos? Well, asbestos fibers cause lesions and scarring on the mesothelium, ultimately leading to the formation of tumors.
The damaged cells secrete large amounts of a clear fluid that presses on the lungs and other organs, causing severe discomfort. The tissue formed by these cells is called mesothelium.There are three main types of malignant mesothelioma: epithelial, sarcomatoid and mixed. The epithelial type is the most common. Mesothelioma is a horrific disease where a particular type of cell (the mesothelium) divides without control.This division of cells can lead to mesothelioma.
Now, not everything is bad news. Benign mesothelioma may occur wherever there is mesothelium. It is localized and does not spread to nearby tissues. Cancer that occurs in the mesothelium tissue is called mesothelioma . Malignant cells develop in the mesothelium, a protective lining that covers most of the body's internal organs. The most common site is the pleura (outer lining of the lungs and chest cavity), but mesothelioma may also occur in the peritoneum or the pericardium .
One of the ongoing problems, however, with this remedy is the fact that mesothelium cancer can take years before it starts to show. In some cases, this period has been over 40 years. The mesothelium makes fluid between the two layers that lubricates the movement of the organs it protects. It actually develops in the mesothelium; a thin, double-layered protective sheath that surrounds vital organs and body cavities. The mesothelium that protects the chest and lungs is called the pleura and the mesothelium that surrounds the abdomen is called the peritoneum.
