The relationship between mesothelioma, asbestos and Cancer

The history of asbestos


Asbestos is generally long sequences of compounds of silicate fibres. Asbestos Word actually comes from the Greek word for "Inextinguishable" as they are resistant to heat, fire and chemical as well as non-conductive products. These asbestos unique properties make useful material in many industries, including shipbuilding, automobile construction industries and construction.


In America, asbestos was first mined and used commercially in the end of the 19th century, gaining in popularity with many commercial applications to the 1970s. It was then that his use was finally prohibited for certain uses as the health hazards came to the forefront - even including the manufacture of electric hair dryers.


In 1989, the Environmental Protection Agency (EPA) banned all new uses of asbestos, but uses already established, however, were still allowed. It was designed as a way to slow down and then eliminate the use of asbestos in the United States, but it was cancelled in 1990. Also in 1989, regulations regarding damaged asbestos or exposed in schools were also created.


Even today, asbestos is found in many products including:
pads and brake shoes, tar and roofing shingles roof, Caulk, clutch plates, fire blankets, the test of the fire clothing worn by firefighters and thermal insulation.
Linking asbestos to cancer


Asbestos is the greatest threat to those who regularly work with her because they are more likely to inhaling the fibers. When asbestos is disturbed, as it can occur when it is to be mounted for a particular use, as a section of pipe or wall insulation, small fibers break off and become airborne. In this form, the people around them can easily inhaled fibres.


Once inhaled, asbestos lodges in the lungs and causes an irritation, scarring and abnormal cell growth possible, resulting in tumours and cancer and other symptoms of mesothelioma. Asbestos cancer is also called mesothelioma, because it affects the lining of the organs of the body, known as mesothelium.


Workers in the following trades were the greatest risk of exposure to asbestos and mesothelioma development:
Milling and mining asbestos Naval construction Construction/building, particularly working with insulation Asbestos removal workers Automobile workers Firefighters Asbestos textile manufacturing
