Overview

What is Mesothelioma? What is the difference between pleural mesothelioma and peritoneal mesothelioma?

Malignant mesothelioma is a disease in which a cancerous tumor grows on the mesothelium - the sac lining the internal body cavities. The specific type of mesothelioma is named for the tissue where the cancer started. Pleural mesothelioma starts in the chest, in the pleura that surrounds the lungs (outer lining of the lungs and internal chest wall). It makes up about 70% of mesothelioma cases. Peritoneal mesothelioma starts in the lining of the abdominal cavity.

How do you get malignant mesothelioma?

Mesothelioma is caused by asbestos exposure. Asbestos, once regarded as a miracle mineral, was popular due its lightweight but tough characteristics as well as for its heat-resistant properties. This naturally occurring mineral was used in many commercial and consumer products, from construction materials such as cement, roofing shingles and insulation, to consumer and industrial applications such as hair dryers, automobile brake pads and pipe insulation.

Most people with malignant mesothelioma worked on jobs where they breathed asbestos. Others were exposed to asbestos in a household environment, often without knowing it.
