Mesothelioma - Definition, Types and Risk Factors

Mesothelioma - definition

Mesothelioma is a rare form of lung cancer associated with asbestos and smoking. Most people who develop mesothelioma have worked on jobs where they inhaled asbestos particles, natural material that is made of tiny fibers. Mesothelioma begins in the lining of several organs. This lining is a tissue called mesothelium that protects organ by secreting specific fluid that allows the organs to move. Essentially, it is this specific fluid that allows the lung to move while breathing. In a way, this lining, the mesothelium acts as a lubricant between organs.

Risk factors for mesothelioma

In all cases that involve mesothelioma, 9 out of 10 cases can be attributed to asbestos. By breathing in fibers of asbestos, the risk of getting the cancerous disease increases.

Examples of at-risk occupations and living areas are as following:

• Asbestos product manufacturing (insulation, roofing, building, materials)
• Automotive repair (brakes & clutches)
• Construction/contractors
• Maritime
• Miners
• Offshore rust removals
• Oil refineries
• Power plants
• Auto Mechanics
• Boiler makers
• Bricklayers
• Building Inspectors
• Carpenters
• Drywallers
• Electricians
• Floor Coverings
• Furnace Workers

Types of Mesothelioma

• The most common form of mesothelioma is "pleural mesothelioma" which deals with the lungs, making up about 75% of mesothelioma cases according to the American Cancer Society. Of patients with pleural malignant mesothelioma, 77% have been exposed to asbestos in the past;
• The second form of mesothelioma is "peritoneal mesothelioma" which deals with the abdomen. The disease makes up about 10–20% of mesothelioma cases. With this type of mesothelioma, the lining of the abdomen - known as the peritoneum - is affected;
• The third and the rarest form of mesothelioma is "pericardial mesothelioma" which deals with the heart.
