Mesothelioma Asbestos - asbestos disease mesothelioma legal information

Exposure to asbestos may increase the risk of asbestosis, lung cancer, mesothelioma, and other cancers. Smokers who are also exposed to asbestos have a greatly increased risk of lung cancer. The main risk factor for developing mesothelioma is exposure to asbestos . Asbestos refers to a family of magnesium-silicate mineral fibers. Previously, asbestos was used widely for insulation because it does not conduct heat well and it is resistant to melting or burning.

As the link between asbestos and mesothelioma has become well known, the use of this material has decreased. However, up to 8 million Americans may already have been exposed to asbestos.

The National Institute of Cancer states that people who have been subjected to asbestos exposure is at major risk for mesothelioma cancer. Nearly 80% of those who have been diagnosed with mesothelioma have been exposed to asbestos. Studies have shown that exposure to asbestos for as little as one to two months can result in mesothelioma appearing decades later

Mesothelioma - Asbestos: Who is at risk?

Nearly everyone is exposed to asbestos at some time during their life. However, most people do not become ill from their exposure. People who become ill from asbestos are usually those who are exposed to it on a regular basis, most often in a job where they work directly with the material or through substantial environmental contact.

Since the early 1940s, millions of American workers have been exposed to asbestos. Health hazards from asbestos fibers have been recognized in workers exposed in shipbuilding trades, asbestos mining and milling, manufacturing of asbestos textiles and other asbestos products, insulation work in the construction and building trades, brake repair, and a variety of other trades. Demolition workers, drywall removers, and firefighters also may be exposed to asbestos fibers. As a result of Government regulations and improved work practices, today's workers (those without previous exposure) are likely to face smaller risks than did those exposed in the past.

Although it is known that the risk to workers increases with heavier exposure and longer exposure time, investigators have found asbestos-related diseases in individuals with only brief exposures. Generally, those who develop asbestos-related diseases show no signs of illness for a long time after their first exposure. It can take from 10 to 40 years for symptoms of an asbestos-related condition to appear.

There is some evidence that family members of workers heavily exposed to asbestos face an increased risk of developing mesothelioma. This risk is thought to result from exposure to asbestos fibers brought into the home on the shoes, clothing, skin, and hair of workers. This type of exposure is called paraoccupational exposure. To decrease these exposures, people exposed to asbestos at work are required to shower and change their clothing before leaving the workplace.

Mesothelioma - Asbestos lung cancer : How great is the risk?

Not all workers exposed to asbestos will develop diseases related to their exposure. The risk of developing asbestos-related diseases varies with the type of industry in which the exposure occurred and with the extent of the exposure. Asbestos that is bonded into finished products such as walls and tiles poses no risk to health as long as it is not damaged or disturbed (for example, by sawing or drilling) in such a way as to release fibers into the air. When asbestos fibers are set free and inhaled, however, exposed individuals are at risk of developing an asbestos-related disease.

In addition, different types of asbestos fibers may be associated with different health risks. For example, results of several studies suggest that amphibole forms of asbestos may be more harmful than chrysotile, particularly for mesothelioma. Even so, no fiber type can be considered harmless, and people working with asbestos should always take proper safety precautions to limit exposure.

Mesothelioma - Asbestos: How does smoking affect risk?

Many studies have shown that the combination of smoking and asbestos exposure is particularly hazardous. Smokers who are also exposed to asbestos have a greatly increased risk of lung cancer. However, smoking combined with asbestos exposure does not appear to increase the risk of mesothelioma.

There is evidence that quitting smoking will reduce the risk of lung cancer among asbestos-exposed workers. People who were exposed to asbestos on the job at any time during their life or who suspect they may have been exposed should not smoke. If they smoke, they should stop.
