What is Mesothelioma?

Mesothelioma refers to progressive growth of malignant cells found in the mesothelium, a thin sheet that covers and protects the vital organs of the body, such as the lungs.

When an abnormal cell is transformed by the genetic mutation of the cellular DNA, cancerous cells are formed. The cells infiltrate the tissues that surround them and gain access to lymph and blood vessels, which carry the cells to other areas of the body.



Normally, cancerous cells that develop in the mesothelium and eventually lead to mesothelioma are caused by glass-like particles that stick in the lungs. These particles come from asbestos, the common element used in building infrastructures. Asbestos is very popular in the industrial and construction field because of its high resistance against fire.



People who are exposed to asbestos have been found out to be the common patients diagnosed with mesothelioma. This is because the particles from asbestos that stick within the lungs tend to create cancerous cells. The damage caused by the process develops a disease process that triggers the growth of cancerous cells, where cell membranes are altered.
