9 out of every 10 cases of mesothelioma have history of asbestos exposure. Although the link between asbestos and What is Mesothelioma Causes – Asbestos Exposure had been established only in the 1960s, as early as 1st century AD Greeks already noticed that slaves who worked in asbestos cloth weaving exhibited sickness of the lung.

Asbestos is a naturally-occurring mineral fiber that became extremely popular with builders and manufacturers in the late 1800s because of its resistance to heat, electricity, tensile strength, and yet pliable enough to be woven like strings. As such, it is used in a wide range of building construction materials such as vinyl tile floors, gaskets, fireproofing, clutch plates, and thermal pipe insulation.

There are two primary types of asbestos used commercially: serpentine and amphibole. What is Mesothelioma Causes – Asbestos Exposure ,Serpentine is characterized by curly and flexible fibers, and so can be spun into fabrics.

Amphibole, on the other hand, is characterized by longer, straighter, and thinner fibers and is often used to produced ceiling pipes and thermal insulation.

When asbestos is fractured or disturbed, this releases smaller and lighter fibers that become airborne and easily breathed in.

Some of the shorter fibers are easily cleared out when they adhere to mucus in various respiratory organs such as the nose, throat, and airways. Coughing, sneezing, and swallowing are some of the ways the fibers are expelled from the body.

Longer and thinner fibers, however, are more difficult to expel once they reach airways of the lungs what is Mesothelioma Causes – Asbestos Exposure . Eventually, the fibers reach the lining and protective sac of the pleura, causing cellular damage or irritation of the pleura as they settle in the lungs.

Mesothelioma Causes – Asbestos Exposure (erpentine and amphibol)

What is Mesothelioma Causes – Asbestos Exposure Attempting to break and remove them, the presence of fibers in the pleura causes irritation of the lungs, often leading to the formation and development of pleural mesothelioma.

There are also some theories proposing that the action of swallowing or coughing causes fibers to reach the digestive lining and abdominal walls (peritoneum). The fibers also cause irritation of the abdominal mesothelium.

As it is with pleural mesothelium, some research show that peritoneal mesothelioma is a result of the physical irritation of the abdominal lining rather than by a chemical reaction caused by contact between fibers and body organ.

Direct exposure and secondary exposure to asbestos have been known to cause mesothelioma. People who have worked in construction, ship building, plumbing, automotive industry, boiler-making, asbestos factories, and those who have lived near asbestos factories are those considered to have direct exposure to asbestos. Some family members of people who have worked in industries that use or produce asbestos are also known to have developed mesothelioma.

Though asbestos had been banned in many countries, there are still places like Japan where asbestos is still widely used in manufacture.
