What is Mesothelioma?

Mesothelioma is a cancer found in the lining surrounding the lungs, the stomach, the heart or the testicles. This cancer takes its name from the name that is given to this lining - the mesothelium. There are roughly 3,000 new cases of mesothelioma in the United States every year. Currently, the primary cause of mesothelioma is exposure to asbestos.

Types of Mesothelioma

Pleural Mesothelioma

The cancer starts in the lining around the lungs (called the “pleura”). This is the most common type of mesothelioma.

Peritoneal Mesothelioma

The cancer starts in the lining around the stomach.

Pericardial Mesothelioma

The cancer starts in the lining around the heart. This type of mesothelioma is very uncommon.

Testicular Mesothelioma

The cancer starts in the tunica vaginalis - the serous membrane that surrounds the testis.

Mesothelioma Symptoms

Mesothelioma is a cancer found in the lining surrounding the lungs, the stomach, the heart or the testicles. The primary cause of Mesothelioma is asbestos exposure. Most mesothelioma symptoms take decades to appear after exposure to asbestos occurred. The symptoms of mesothelioma are also found in many other other more common diseases, making mesothelioma hard to diagnose.

Mesothelioma symptoms vary with each stage and location (chest, abdomen, heart) of the disease. Mesothelioma is unique in that it has a long latency period, which is the amount of time between the initial exposure to asbestos and the appearance of noticeable symptoms. The latency period for most symptoms caused by mesothelioma ranges from 10 to 60 years.
