It is in the chest and abdominal cavities, as well as in the cavity around the heart (pericardial sac), where is a layer of specialized cells called mesothelial cells. These cells also surround the outer surface of most internal organs. Mesothelium is what this cells form!
The mesothelium performs a (protective) function for the internal organs by producing a some fluid lubricating that lets the organs to move around. Like, this fluid makes it easier for the lungs to move inside the chest while a person breathes. The mesothelium of the abdomen is known as the peritoneum, and the mesothelium of the chest is called the pleura. The pericardium refers to the mesothelium of the pericardial cavity.
There are three primary types of malignant mesotheliomas:
Epithelioid. About 50% to 70% of mesotheliomas are of this type and have the best outlook for survival.
Sarcomatoid. Approximately 7% to 20% of cases are of this type.
Mixed/biphasic. From 20% to 35% of mesothelioma cases fall into this category.
Approximately three-fourths of all mesotheliomas begin in the chest cavity and are known as pleural mesotheliomas. Peritoneal mesotheliomas begin in the abdomen, and make up around 10% to 20% of all cases. Mesotheliomas arising in the cavity around the heart are quite rare.

Who Is At Risk of Mesothelioma?
Here i give You some infos from another page.
previous exposure to The only known cause of mesothelioma is asbestos fibers. Often times workers are not told they are working around asbestos, and even single exposures to very low doses of fibers can produce serious long-term consequences.
Asbestos diseases are said to follow the trail of exposure. That means that wherever people have received asbestos exposure, regardless of their trade, age, sex or race, they are at risk of cancer and other diseases.
Almost anyone dust is at risk. Even a who has inhaled asbestos worker's families and friends can be at risk, because asbestos can often be carried on clothing.
Exposure to asbestos dust can occur at major construction job sitesor renovation of commercial buildings, in shipyards, , and the numbers of people in such occupations contracting asbestos disease are high.in industry, and during construction . See the list at right for certain occupations that are known to be those where risk of exposure to asbestos is great
