MESOTHELIOMA

Several decades ago, a known fibrous ore under the name of asbestos was usually employed in many industries for the manufacture much of products. A natural ore, asbestos was strongly evaluated for its tensile strength; heat strength and to the damage of chemicals; and its low electric conductivity.

Because of its inherent properties, asbestos became component very common of heat and electric insulation, particularly in the metallurgical construction industry, naval construction, and industries. Before long, asbestos could be found in the dry partition, insulation of ceiling, brake linings, putting balance of the trimmings, boilers of the boat, and more.

However all was not good.

Even with beginning of the year 90, the scientists and the doctors had noted to worry health issues among manufacturers of ships, workers of construction, minors, and other professionals frequently exposed to asbestos. By the mid- with late-1990, it was obvious that asbestos was dangerous.

Today, we know that the exposure to fibres and the asbestos dust has the potential to cause a mortal cancer called the mesothelioma.

Which is mesothelioma?

The mesothelioma is a cancer which attacks the lining of the lungs, the cavity of trunk, and other internal bodies. When a person breathes in asbestos fibres, the fibres become imprisoned inside and irritate this sensitive, known lining under the name of mesothelium. With time, the cells of mesothelium become marked, ignited, and thereafter - cancer patients.

The most common form of mesothelioma is a pleural mesothelioma, which attacks the lining mesothelial lungs. Other types of the cancer include the mesothelioma p�riton�al, which affects the lining of the abdominal cavity, and the pericardial mesothelioma, which attacks the lining of the heart. From these three, the pericardial mesothelioma is rarest, occurring in less than 1% of all the cases.

Symptoms and forecast

The mesothelioma often takes decades to develop. A worker of the construction which was exposed to the excessive quantities of asbestos can not test any serious symptoms of the mesothelioma during 15,30, or even 50 years. Even when the symptoms appear, they are frequently nonspecific, including:

• Pain of trunk
• Difficulty breathing
• Persistent cough
• Brevity of breath
• Ingestion of difficulty
• Fever

Unfortunately, the inaccuracy of the symptoms of mesothelioma makes the disease manifestly difficult to catch with its parts. Before a victim of mesothelioma receives a diagnosis, cancer is likely to be with a advanced stage. Consequently, the forecast for cancer is often extremely poor. According to some studies, the rate of five years survival among victims of mesothelioma can be less than 30%, according to the particular shape of cancer patient A.
