Mesothelioma Causes

What Causes Mesothelioma?

Mesothelioma is a cancer that occurs in the mesothelium, a thin membrane encompassing the body’s internal organs and cavities. Mesothelioma is caused by asbestos exposure. Asbestos fibers that are inhaled through the mouth and nose may eventually become embedded in the lining of the lungs, causing harmful inflammation of the pleura and resulting in mesothelioma or asbestosis (scar tissue formation in the lungs).


Workers often brought home dangerous asbestos fibers on their clothing, hair, or person. Those who came into contact with these fibers on the person or their clothing have developed mesothelioma as a result.
