Learning About Mesothelioma - The Basics

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.

Causes of Mesothelioma

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.

Asbestos exposure doesn't result immediately in cancer. It takes years for the cancer to form and cause symptoms. Workers exposed in the 1950's, 60's, and 70's are just now being diagnosed with mesothelioma.

Keep in mind that some people do not display any symptoms. If you have been exposed to asbestos, please talk about your risk factor with your doctor. Together, you can make informed choice in your personal healthcare.
