Asbestos is a carcinogenic, fibrous mineral, which is at times used in construction, usually for insulating purposes. People who live or work in conditions where they are exposed to asbestos fibers run the risk of developing mesothelioma. Despite its health hazards, asbestos is often used in construction due to the fact that it is relatively a cheap material.

Consequently, construction workers exposed to the mineral, as well as their families, are most at risk of developing this rare form of cancer. Workers bring home the carcinogenic fibers as traces on their clothes, thereby exposing family members to the danger of developing the cancer. A few weeks of exposure to asbestos can be enough to cause mesothelioma. However, in general mesothelioma has a latency period of 35-40 years from the time of exposure to asbestos to the actual development of symptoms.

Older buildings that have exposed insulation that contains asbestos, or other areas where asbestos fibers are disturbed or exposed, need to be checked by professionals and repaired or removed. Asbestos fixed firmly and used as insulation within enclosed areas such as walls and pipes is not likely to pose a health hazard with regard to malignant pleural mesothelioma, as long as it is not sawed, drilled or in any other manner that could cause the asbestos fibers to be diffused into the air, and be breathed in.

There is no safe level of exposure. Consequently, people who work with asbestos need to ensure that they are protected from exposure and that they do not bring asbestos dust on their clothes home to their families. Smoking, together with exposure to levels of asbestos can increase the chances of this cancer developing. However, not all those exposed to asbestos develop mesothelioma cancer, as genetic factors are involved.

Mesothelioma asbestos poisoning is usually fatal, and death often results within a relatively short span of time from the period when the symptoms first manifest themselves. Overall in the United States, the number of cases of mesothelioma cancer is on the rise.
