What is Mesothelioma?

Malignant mesothelioma is a type of cancer that forms in the lining of the chest or abdomen. The cancerous cells develop in the pleura of the lungs, or the peritoneum of the abdomen.

There are three types of mesothelioma:

• Peritoneal
  
  
• Pleural
  
  
• Pericardial

Pleural mesothelioma is the most common type of the disease, followed by peritoneal, then pericardial.

Asbestos exposure is the number one cause for mesothelioma. Asbestos is a mineral that was once found in many types industrial supplies and equipment. Asbestos was used until the mid 1970's when the risks of exposure were becoming evident.
