Mesothelioma Disease, Mesothelioma Types

The cavities within the body encompassing the chest, abdomen, and heart are surround by a membrane of cells known as the mesothelium. Mesothelial cells assist in general organ functions. The mesothelium is particularly important to organs which are commonly in motion, such as expansion or contraction of the lungs, stomach, or heart. Lubrication from the mesothelial cells allows free range of motion within the body.

The mesothelium of the chest, abdomen, and cardiac cavity are called the pleura, the peritoneum, and the pericardium, respectively. Each of these groupings of mesothelial cells are extremely critical to the functions of the body structures which they encompass.

While tumors of the mesothelium were first recognized in the late 18th century, it was not until the middle of the 20th century that this particular cancer was studied and examined with more detail. It was at this time where suspicions of the cancer’s causal relationship with asbestos exposure became more substantiated. A joint study through the Department of Thoracic Surgery at the University of the Witswaterand/Johannesburg General Hospital in South Africa provided the most compelling evidence of the nexus between asbestos exposure and the development of pleural mesothelioma.
Mesothelioma Cancer

Incidence of mesothelioma is still quite rare, with only 2,500-3000 diagnoses in the United States each year. There was a spike in reported diagnoses between 1970 and 1984, which has been attributed to the latency period between diagnosis and the height of industrial exposures- which occurred roughly 40-60 years prior to this time. Exposure was common in nearly all industries but was particularly common in the WWII-era military industrial cycle, including Navy Shipyards
