Cancer and Mesothelioma 2

The most common form of cancer caused by asbestos is mesothelioma, a rare cancer that is very rarely cured. The only proven cause of mesothelioma is exposure to asbestos.

An estimated 20 to 30 percent of people diagnosed with mesothelioma have no knowledge of prior exposure to asbestos. But the prior popularity of asbestos as a building material may shed some light on a person's ability to identify the source of their exposure to asbestos.

Mesothelioma typically attacks the thin membranous lining of the lungs, abdomen, or heart, known as the mesothelium. It is estimated that 2,000 to 3,000 new cases of mesothelioma are reported each year. The symptoms of mesothelioma typically arise 20 to 50 years after exposure, which makes it difficult to diagnose the countless cases lying dormant across the country.

Mesothelioma Lung Cancer

Mesothelioma and lung cancer are both serious illnesses, but they are not the same. Mesothelioma – sometimes called “asbestos lung cancer” – is really not a form of lung cancer because it does not develop in the tissue of the lungs. Instead, it is a cancer of the lining that surrounds the lung (the “pleura”).

Mesothelioma is caused almost exclusively by asbestos exposure. It is considered a “signature disease” for asbestos exposure, which means that, if you have mesothelioma, it can be assumed that you had exposure to asbestos at some point in your life. Smoking does not cause mesothelioma.
Lung cancer can be caused by asbestos exposure; it can also be caused by smoking. In fact, someone who smokes and was exposed to asbestos has a much higher risk of getting lung cancer. See Asbestos and Smoking.
