Americans Probably Not Quite Sure What Mesothelioma is.

"Most Americans are probably not quite sure what mesothelioma is. Many though, can probably associate the word mesothelioma with an attorney or possible litigation. As I flip through the channels on my television set, I too, notice that mesothelioma is frequently mentioned by law firms. However, the focus of this article is to educate the public on what mesothelioma is."

Mesothelioma can either be malignant (cancerous) or benign (non-cancerous) in nature. Mesothelioma affects the mesothelium, hence mesothelioma.

What is the mesothelium?The mesothelium is a type of tissue lined with special cells referred to as mesothelial cells. The mesothelial cells typically line the abdominal cavity, heart cavity, chest cavity, and the outer surface of most internal organs. Each cavity has a specific name for the mesothelial covered cavity which is:

  • Peritoneum: abdominal cavity
  • Pleura: chest cavity
  • Pericardium: heart cavity

The mesothelium has a specific purpose in the body. The mesothelium produces a lubricating fluid that allows easy movement of the organs. The pleural mesothelium for example, allows the lungs to move easily with each breath that is taken. Without this, breathing would be a difficult and possibly painful process.

Many refer to malignant mesothelioma as simply, mesothelioma. There are three main types of malignant mesothelioma ranked from less likely to more commonly seen:

  1. Sarcomatoid
  2. Mixed/Biphasic
  3. Epithelioid

Malignant mesothelioma more commonly begins in the chest cavity (pleural mesothelioma). Approximately 10-20% of the cases of malignant mesothelioma will begin in the abdominal cavity (peritoneal mesothelioma). Malignant mesothelioma rarely begins in the cavity surrounding the heart (pericardial mesothelioma).
