Updated July 24, 2013

Definition:

Mesothelium is the layer of tissue (membrane) that surrounds certain organs of the body.

This tissue is divided into 3 primary regions:

  • The pleura - the lining around the lungs
  • The pericardium - the lining around the heart, and
  • The peritoneum - the lining around the abdominal cavity

Mesothelioma is a type of cancer that begins in the mesothelium. It is most common in people who have been exposed to asbestos, and continues to increase in incidence worldwide.
