Types of Mesothelioma

Tumors of the mesothelium may be benign or malignant. Benign tumors are relatively harmless. Malignant tumors are extremely dangerous, because they will spread to other areas of the body over time. The term “mesothelioma” is generally understood to refer to malignant mesothelioma. The area of the mesothelium most likely to develop a malignant tumor is the pleura, or the lining of the chest cavity surrounding the lungs. When this occurs, the victim is diagnosed with pleural mesothelioma. About ten percent of victims initially develop tumors in the abdominal region, or peritoneum. This results in a diagnosis of peritoneal mesothelioma. Very rarely, the cancer may originate in the mesothelium around the testicles or the heart cavity. As with all cancers, it is possible for the disease to spread to other areas of the body.

Did you know: Scientists are developing new methods of attacking cancer. Because mesothelioma is a rare form of cancer and does not respond well to conventional treatments, the FDA allows pharmaceutical companies to try new compounds on mesothelioma patients.

Fact: In the past two years, about 5000 Americans have been diagnosed with mesothelioma.
