exposure to asbestos is a common cause of mesothelioma. Almost all cases of mesothelioma are caused by exposure to asbestos. Asbestos is a natural mineral that is mined from rock found in many countries around the world. It is made up of tiny fibers as strong as steel, woven like cotton and is very resistant to heat, chemicals and electricity.
is the first definite link between mesothelioma and asbestos was made in 1960. At that time, asbestos is very widely used in the manufacture of insulating materials such as insulation boards and building materials, including cement.
When asbestos is damaged or disturbed, it releases small fibers, almost invisible to the naked eye, which, when in the air can be breathed in, and can not be discharged or coughed up. After the fiber is found in the lungs, a defense mechanism tries to break them down and remove them, which leads to inflammation in the lung tissue.
of asbestos fibers can also penetrate the lung tissue to settle in the pleura (the membrane surrounding the lungs). For many years they can cause asbestosis, mesothelioma or other lung disease to develop. Asbestos fibers also can be swallowed, and some of the fibers are lodged in the digestive system. They will then move into the membrane that lines the abdomen (peritoneum), where they cause inflammation.
Those individuals most likely to have been exposed to asbestos will include: construction workers, Boilermakers, construction workers, demolition workers, electricians, Plumbers, builders, etc. Family members of those who worked with asbestos and unknowingly brought home asbestos dust on their clothing, will also be at risk, and is also known that developed mesothelioma.
There are three types of asbestos, including: blue, brown and bijela.Plave and brown asbestos are the types most commonly associated with mesothelioma, and are now very rarely used. However, although originally, white asbestos is thought not to be dangerous, recent studies have shown that it is harmful.
Although by 1999 the import and use of all asbestos was banned due to mesothelioma develops so slowly, and it is estimated that by the year 2015, about 3,000 people are diagnosed with mesothelioma every year. After this time, the number of people who develop mesothelioma will begin in the fall of each year.
mesothelioma usually develops many years after initial exposure to asbestos. Although it may take as 10-60 years, average time is about 30-40 years after asbestos exposure.
Occasionally, mesothelioma will be diagnosed in people who have never had any history of asbestos exposure. Other causes of disease are still not fully understood, but in rare cases, mesothelioma has been linked to radiation exposure.
Studies have shown that there is no evidence that smoking increases the individual's risk of developing mesothelioma. It is understood that exposure to other construction materials, for example, fiberglass and will not increase the risk. Mesothelioma is not contagious and therefore can not be transferred to another person. Family members are at risk when in contact with asbestos particles.
