Asbestos initiate tissue scarring and acting as a carcinogen, which was found in the early 19th century and became generally accepted in the sixties of the 19th century.

WHEN IS harmful?:
It is a siliceous mineral fiber, which can be found in nature. Because of their physical chemical properties, particularly resistance to combustion, its use of mid-19th century, is very extensive.

It becomes harmful to us, if the use or treatment is in a relaxing environment and we are exposed to it with inhalation. Asbestos fibers, which we breath, remain in the lungs and can cause disease. With some probability we can become sick, but in the first place that depends on the quantitative burden of lung asbestos dust and the biological properties of the organism, requiring that some more and others less susceptible to the action of an agent. Anyone who has been exposed to inhaled asbestos dust, therefore, do not get sick. Scarring of the lungs can be expected particularly in those with a high lung burden of asbestos. In the operation of a carcinogenic asbestos is not clearly the interdependence of the quantitative load of the lungs by asbestos and can be expressed also in less time after exposure to asbestos dust.

Asbestos fibers become harmful to health when entering into the organism. Most of them are taken by breathing. Fibers of asbestos triggered in tissue inflammation, which results in the formation of scar tissue and malfunction in cancer tissue.

The development of the disease
The disease develops with latency of several decades. Asbestos fiber, which we breath, stay in the lungs and remain in a position where it is located, life raises focus inflammation and can potentially cause development of cancer in the lungs.

The onset of the 20^th century saw hectic building activity at construction sites, ship yards, rail yards. Asbestos fibers were used as a major component and its production was also stepped up to meet the ever increasing demand. Mankind got exposed to asbestos in its early years of development and very soon, incidents of lung cancer also came to be reported. However, the condition of mesothelioma is believed to have its origins at places where wastes from mine extraction containing a lot of asbestos fibers were used as dumping material to envelop playgrounds and other open spaces. It was around this time that people who had practically no chance of getting exposed to asbestos fibers started developing symptoms of this disease. Though many officials were aware of the potential dangerous effects of asbestos mining much earlier, the activity continued and was formally brought to a close only in 1966.

During those times, mines were permitted to operate without basic safeguards and the concept of hygienic and safe work practices were relatively unknown. Due to this lack of adequate safety nets, many workmen began experiencing symptoms of mesothelioma on a yearly basis. What was more worrying was the fact that many cases that were diagnosed were of people who got it through the secondary route, having not been exposed to asbestos directly.

Mesothelioma saw its first case at an Australian mine and that worker had been working in that mine for about three years. Things then began to deteriorate rapidly as people inhabiting the town where asbestos mining was being carried out started exhibiting symptoms and this continued well into the 1970s, when the Australian Government took a long pending decision to shut it down. Unfortunately, the damage had been done and many people had fallen prey to this dangerous disease.

The tragedy just highlights the fact that if proper safeguards in the working environment had been implemented at that time, history would have had a different story to tell.
