Each year, nearly 3,000 people in the United States are diagnosed with mesothelioma cancer. Virtually all cases of malignant mesothelioma are linked to asbestos.

So what is mesothelioma? Malignant mesothelioma is a rare form of asbestos lung cancer that most often occurs in the thin membrane lining the lungs, chest and abdomen. Malignant mesothelioma attacks the membranes, called mesothelium, that surround and protect vital organs like the lungs and heart. These cancerous mesothelioma cells can metastasize (spread) quickly to other parts of the body.

There are several types of mesothelioma, including:

One of the most important mesothelioma facts is that is is a particularly dangerous disease because it has a very long latency period. Mesothelioma cancer symptoms may not appear for 10, 20 or even 40 years after exposure to asbestos. In addition, once symptoms do appear mesothelioma progresses quickly. According to the American Cancer Society, many victims die within two years of being diagnosed with mesothelioma.
