It was made in 1960 the first definition defines the relationship between mesothelioma and asbestos. In the past, asbestos was imported into Britain in large quantities. It is used in construction, shipbuilding and home appliances. Asbestos was widely used in insulation materials, such as amosite insulation board, and building materials, including asbestos cement.
When asbestos is disturbed or damaged by releases tiny fibers that can be inhaled into the lungs. Asbestos fibers are very thin and if inhaled, they can make their way into the smallest airways of the lungs, so they can breathe or cough Out. Once the fibers in the lungs, the protective mechanism of the body attempts to destroy and remove them, which leads to inflammation of lung tissue.
Asbestos is the most common cause of mesothelioma. Up to nine out of ten cases of mesothelioma caused by asbestos exposure. Asbestos is a natural mineral extracted from rock found in many countries. It consists of tiny fibers that are as strong as steel but can be woven like cotton and are highly resistant to heat and chemicals.
Asbestos fibers can also penetrate the lung tissue to settle in the pleura (membrane surrounding the lungs). For many years, they can cause mesothelioma or other lung disease to develop.
Asbestos fibers can be swallowed, and some fibers can get stuck in the digestive system. Then they can pass through the membrane lining the abdomen (peritoneum), where they cause inflammation.
Those most likely been exposed to asbestos are:
People who have worked in other places where asbestos was present and
people who lived near asbestos factories.
Family members who worked with asbestos, and lead to a reduction of dust on their clothes also sometimes developed mesothelioma.
There are three types of asbestos: blue, brown and white. Blue and brown asbestos types most commonly associated with mesothelioma. Currently, they are rarely used and can not be imported into the United Kingdom. Originally, white asbestos is not thought to be dangerous, but recent studies have shown that it is also harmful.
In 1980, imports of blue and brown asbestos in the United Kingdom were arrested and in 1999, the import and use of asbestos was banned. However, as mesothelioma develops so slowly, it is estimated that by 2015 about 3000 people will be diagnosed with mesothelioma every year. The number of people who develop mesothelioma begins to decline every year.
Mesothelioma does not usually develop until years after exposure to asbestos. It can take at any time from 10 to 60 years, but the average is about 30 to 40 years after exposure to asbestos.
Occasionally, mesothelioma develops in people who have never been exposed to asbestos. Other causes of disease are not fully understood, but in rare cases, the development of mesothelioma has been linked to radiation exposure.
Studies have found no evidence that smoking increases the risk of mesothelioma. We also believe that the impact of other construction materials such as fiberglass does not increase the risk.
Mesothelioma is not contagious and can not be transferred to third parties. This is not caused by defective genes, and inherited that family members have an increased risk of disease if they have not been in contact with asbestos.
