How asbestos creates mesothelioma?

Malignant mesothelioma is caused by asbestos exposure. Many people with mesothelioma have worked or lived in places where they inhaled or swallowed asbestos. Other risk factors for malignant mesothelioma include the following:
• Living with a person who works near asbestos.
• Being exposed to a certain virus. After being exposed to asbestos, it usually takes a long time for mesothelioma to occur. There is a latency period of 20 to 50 years or more between initial exposure and development of the disease with the average being between 35 and 40 years. Rare instances have been documented when the interval was less than 20 years.The incidence of mesothelioma rises with the intensity and duration of exposure to asbestos. However, there are numerous cases of mesothelioma among people with very little occupational exposure or even household exposure. There are cases of people getting mesothelioma 30 or 40 years after a summer job working construction, and cases of wives or children being exposed from work clothing. Many people were diagnosed with mesothelioma now were exposed in the Navy many years ago unknowingly.
