What is asbestos? Asbestos disease, mesothelioma cancers, lung cancer and asbestosis are the diseases caused by asbestos. Asbestos was one of the most common industrial materials put to use in the twentieth century. It also proved to be one of the most deadly, that inhalation of asbestos fibers can lead to a variety of lung problems such as asthma and asbestosis – and can also be the direct cause of mesothelioma.
Asbestos constitutes different naturally occurring mineral fiber in some rocks and soil. It has found wide use in industries and building materials such as fireproofing, roofing shingles, electric insulation, furnace, hot pipe covering, and friction products.
However, recent studies have revealed that exposure to asbestos may have adverse consequences for health from asbestos disease and mesothelioma for workers in industries making use of asbestos as well as those living in the environment of such places. Workers may inhale particles of asbestos fibers into the air, they also become exposed through skin contact with asbestos or by swallowing asbestos fibers while working. These workers are vulnerable to asbestos diseases mesothelioma and asbestosis.
Mesothelioma is the most serious of several asbestos-related diseases detected so far. It is because of the carcinogenic effect of asbestos particles. Mesothelioma is caused by exposure to asbestos occurs when asbestos fibers are inhaled or ingested and lodge in human tissues, causing inflammation or infection. Asbestos is a naturally occurring fibrous substance that was once widely used in the 20th century in a number of different industries. When the public became aware of the dangers associated with the mineral, warnings were issued in the mid-1970s and the use of the product began to decline.
Asbestos can cause lung cancer, esophagus, colon, rectum, stomach, vocal cords, and kidneys. About 70 percent to 80 percent of all cases of asbestos disease mesothelioma – a rare type of cancer of the mesothelium, the membrane that covers and protects most internal organs of the body – are the result of exposure to asbestos at work.
mesothelioma asbestos disease are not immediately apparent. The asbestos particles can remain dormant in the body for many years and manifest later, when the prognosis is very poor. It is possible that when the disease is diagnosed, the cancer may have already spread significantly.
The first case of asbestos disease mesothelioma was filed 70 years ago. Employees in industries with considerable risk of asbestos poisoning are, in principle, entitled to compensation mesothelioma. The compensation is only available to employees who are at risk of exposure to asbestos since the 1940s. Recently, many mesothelioma patients have filed lawsuits for compensation. They were compensated on the basis that the owners of industries continued to use asbestos despite the information from the health risks that result.

The main cause of mesothelioma is exposure to asbestos. A known history of asbestos is present in 70-80% of mesothelioma cases. There are about five times more in men than in women. This is probably because many cases were caused by exposure to asbestos at work.
The risk of developing mesothelioma increases with the amount of exposure to asbestos. Asbestos is made up of tiny fibers. You can breathe these fibers when you come into contact with asbestos. Some of the fibers that have been instilled in sputum and if swallowed. The fibers work their way into the pleura lining of the lung. They irritate the pleura and may cause genetic changes that lead to cancer growth.
However, genetic factors also play a role in determining the state that develops. In general, cancer begins when a series of genetic mutations occur in a cell, causing the cell to grow and multiply out of control. That’s probably why all those exposed to high levels of asbestos do not develop mesothelioma.
It is likely that mesothelioma due to interaction between several factors, such as hereditary diseases, your environment, your health and your life choices. Here are other factors that can lead to getting mesothelioma include:
Smoking
Although smoking was not associated with the development of mesothelioma, the combination of smoking and asbestos exposure significantly increases a person’s risk of developing mesothelioma.
Radiation
Mesothelioma has been reported in individuals after exposure to radiation therapy using thorium dioxide (Thorotrast). Some studies show an increased risk of mesothelioma among people treated with radiotherapy for cancer before. However, other studies show no increased risk. If radiation therapy increases the risk of mesothelioma, it is likely to occur in a very small number of people.
simian virus 40 (SV40)
This virus was identified in cells of human mesothelioma. Research has examined a virus called SV40. In people who have been exposed to asbestos, some studies have shown that contact with the virus SV40, it is more likely to develop mesothelioma.

Most cases of mesothelioma are caused by exposure to asbestos occurs when asbestos fibers are inhaled or ingested and lodge in human tissues, causing inflammation or infection.
Asbestos likely causes cancer by physically irritating cells. When asbestos fibers are inhaled, they reach the ends of the small airways and penetrate the pleura (lining of the lung). These fibers can then damage the mesothelial cells of the pleura and eventually cause mesothelioma.
Asbestos is a mineral found naturally in the environment. Asbestos fibers are strong and heat resistant, making them useful in a wide variety of applications. Asbestos was widely used in the years after 1945. In the past, asbestos was widely used in the construction industry, the manufacture of ships, automotive, power plants, telephone exchanges, the manufacture of household appliances and many other products. Thus, most cases of mesothelioma occur in men who worked in the manufacturing of asbestos or used asbestos products, including construction and engineering.
Damage caused by exposure to asbestos typically takes 10 to 50 years to show symptoms. When symptoms appear, they are often mistaken for signs of other health problems less dangerous. Many people are not even aware that they were exposed to asbestos.
If you have been directly exposed to asbestos fibers at work or at home, your risk of mesothelioma is greatly increased. People who are exposed to asbestos can carry home the fibers on the skin and clothing. People who work with asbestos should shower and change clothes before leaving work. If you have been exposed to asbestos, your family may also have been exposed. Studies have shown that families of people exposed to asbestos also have a higher risk of developing mesothelioma.

Exposure to asbestos is the main cause of mesothelioma. Asbestos fibers are very fine, if they breathe, they can lodge in every corner of the lungs. They will then remain trapped and can not be evicted or by breathing or by coughing. Sometimes asbestos fibers through the lung to become embedded in the pleura, which may lead to pleural mesothelioma or other lung diseases such as asbestos. Small asbestos particles can also be swallowed and remain in the digestive tract. From there, they will eventually win the peritoneal cavity and cause peritoneal mesothelioma.
A person may be exposed to asbestos:
directly, if it worked in the asbestos industry, or if she lives or works in a building contaminated with asbestos from building materials or other products containing asbestos;
indirectly, if she lives with an asbestos worker and is in contact with asbestos dust deposited on the clothing and hair of workers.
Mesothelioma may take 15 to 40 years to appear after exposure to asbestos. Some people develop the disease without knowing they have been exposed to asbestos. Research is currently underway to determine if other risk factors, such as family history, genetics and personal medical history, could increase the risk of mesothelioma.
