Asbestos – The silent killer


Asbestos is the single biggest work place killer today. People who have worked with the material are at serious risk from developing lung cancer, asbestosis and mesothelioma, fatal respiratory illnesses that debilitate their victims. Evidence of asbestos’ deadly effect on those who breathe its fibres is likely to multiply in the decades to come.

Asbestos was once heralded as the greatest building material available to those in the construction industries. Its high tensile strength, durability and flexibility, as well as heat insulation and fire retardant properties meant that it could save lives, make buildings strong and make industries rich. It was first used by the Greeks some 2000 years ago. They were aware of the health hazards it posed but believed that its magical ability to withstand fire far outweighed this danger.

The dangers to health were all but ‘forgotten’ until at the turn of the twentieth century when medical researchers noticed a large number of deaths and lung problems occurring in asbestos mining towns. In 1917 and 1918, several United States studies discovered that asbestos workers were dying unnaturally young.

Asbestosis was first diagnosed in a 33 year old woman in 1924, this lead to studies being carried out on asbestos workers in the UK. Examinations on the workers showed that thirty percent had asbestos-related lung disease. UK laws were introduced in 1931 to increase ventilation and to make asbestosis an identifiable work related illness.

Despite the established link between asbestos and lung diseases the industry continued to grow well into the last century. At the peak of its usage asbestos was produced in 24 countries worldwide; it was also manufactured in over 100. World production climaxed at over 5 million tonnes. The building, shipping, insulation and demolition companies whose workers came into contact with asbestos were often aware that their staff were at risk. They did not take sufficient steps to protect their workforce from personal injury.

Sadly the effects of asbestos take many years to manifest themselves. People who worked in the construction industries some 20 to 40 years ago may still be awaiting their fate. Asbestos causes several diseases, two of which occur only in those who have had contact with asbestos, asbestosis and mesothelioma. Lung cancer and emphysema are more commonly associated with smoking but frequently occur in non smokers with a history of asbestos contact.

It is thought that the worst is yet to come. The peak of asbestos usage was in the 60’s and 70’s so many people may develop lung diseases in the near future.

Due to the latency of asbestos diseases it is thought that we will be seeing many more incidences of mesothelioma in the next 25 years. Hugh Robertson, head of health and safety at the British TUC says: "A realistic estimate is that within the EU alone 500,000 will die in the next 35 years, half from mesothelioma and half from lung cancer. In Japan, an estimated 100,000 will die. If you add the Australian, Canadian and US figures then even a million is an under estimation – and that is only for the developed countries.”

People affected by asbestos are entitled to compensation from the companies who knowingly exposed them many years ago.

People affected by asbestos related illness should speak to a personal injury solicitor who has experience in asbestos cases.

Types of Mesothelioma

Mesothelioma is a deadly form of cancer that affects the serous membranes surrounding the major organs of the body i.e. the lungs, heart and the abdominal organs, causing these vital organs to inflate with excessive fluid. This fluid further causes the improper functioning of the organs. The only known cause of this cancerous tumor is asbestos exposure. In this disease, malignant cells are built up in the protective linings (serous membranes) of several internal organs known as mesothelium. Different organs in the abdomen cavity can get affected by mesothelioma because of the presence of the protective linings surrounding them. The most common types of mesothelioma include:

* Pleural Mesothelioma,
* Peritoneal Mesothelioma, and
* Pericardial Mesothelioma.

Pleural Mesothelioma:
Pleural Mesothelioma is a tumor in which the lining of the lungs, or lung pleura, gets affected by malignant cells. The pleura is a soft protective tissue that surrounds the lungs in the chest cavity. It helps the lungs in breathing (respiration) by producing a serous fluid that lubricates the pleural surfaces to avoid the teasing of the lungs against the chest wall. The malignant cells, once entered the pleura, begin to spread and affect the surrounding organs and tissues. This leads to further complications resulting pain and severe symptoms. Mesothelioma affecting pleura is of two categories:

Diffused or Malignant (Cancerous):
It is the serious form of pleural mesothelioma that affects the pleural lining of the lungs and its surrounding organs. Localized and Benign (Non-cancerous): It is the non-cancerous form of mesothelioma, which does not affect all parts of the body except the pleura. However, it constricts the lung causing shortness of breath, and in some severe cases, pneumothorax (lung failure).

Peritoneal Mesothelioma:
Peritoneal Mesothelioma is a tumor of the peritoneum membrane or the abdomen lining, affecting many organs in the abdominal cavity including stomach. This form of mesothelioma cancer is less common than the pleural form but is more aggressive, resulting severe symptoms and short life expectancy. Like many other cancers, peritoneal mesothelioma can also be either malignant or benign.

Pericardial Mesothelioma:
Pericardial or Pericardium Mesothelioma is the rarest form of cancer, counting less than 10% of mesothelioma cases. In this form of cancer, fluid gets accumulated in the sac that encloses the heart. The main cause of this disease is the inhalation of asbestos fibers.

Due to the rarity of this disease, doctors and researchers have not clearly understood how the asbestos fibers enter the heart lining or pericardium. The only logical explanation so far about this form of cancer is the possibility of the asbestos fibers, converted into tiny pieces, transported from the lung into the heart by means of blood circulation. Once the asbestos fibers enter the heart, they expand the tissues in the chest cavity and the pericardium with excessive liquid, disrupting the working of the heart and causing chest pains with breathing disorders.

Each year, approximately 2,000 new cases of mesothelioma are diagnosed. At some point of their lives, the patients of mesothelioma have been exposed to asbestos that later cause the hideous cancer of mesothelioma. If you, at some point of your life, have worked in an asbestos-rich environment or used any asbestos materials, you should contact a mesothelioma doctor for correct diagnosis and best treatment options available.
