What are the risk factors for malignant mesothelioma?
There are several risk factors that increase the likelihood that a person will develop mesothelioma. The primary risk factor is asbestos exposure. Exposure to this very harmful substance can significantly enhance the chances of contracting the disease. While smoking does not have a direct causal relationship with mesothelioma, it is a significant compounding factor that increases the likelihood of developing the disease. Other less common secondary factors include exposure to radiation, zeolite, simian virus 40 (SV40), and erionite. Each of these risk factors is discussed in more detail below.

Most Common Mesothelioma Risk Factors
Exposure to asbestos is the leading risk factor associated with mesothelioma. Asbestos is an insulating material comprised of magnesium-silicate mineral fibers. It was favored by builders and contractors for many years for its low heat conductivity and resistance to melting and burning. Since researchers have identified more and more links between mesothelioma and exposure to asbestos, the material is now less widely used. Prior to this discovery, however, millions of Americans have experienced serious exposure to this harmful substance.
Smoking alone is not linked to mesothelioma, but smokers who are exposed to asbestos have a much higher chance of developing asbestos lung cancer (as much as fifty to ninety percent higher) and as much as double the risk of developing mesothelioma.Sources
