Asbestos: Cause Of Deadly Mesothelioma



by: Kirsten Hawkins
A View of Mesothelioma
Asbestos is the commercial name given to certain types of fibrous materials. They are silicates of varying compositions; the silica combined with such bases as Magnesium, Iron, Calcium, sodium and Aluminum. Asbestos fibers are usually from 20 to 500  in length and 0.5 to 50 in diameter. Asbestos bodies appear as golden brown or beaded rods with a translucent center. The fibers are insoluble. The exposure of asbestos causes fibers to be inhaled and fine dust deposited in the alveoli inside the lungs consequently causing a type of cancer called Mesothelioma (a deadly tumor) involving Mesothelial tissues or usually cells of lungs or stomach and abdominal organs.

Mesothelioma is a rare form of cancer of the Pleura (lung cancer) and Peritoneum (abdomen cancer). 
 
Mesothelioma has been shown to have a strong association with the crocidolite variety of asbestos. Pleural mesothelioma, the most common manifestation of asbestos exposure, is well-circumscribed plaques of dense collagen, often containing calcium. Peritoneum Mesothelioma may or may not contain asbestos bodies and rarely do they occur in persons who have no history or evidence of asbestos exposure.

Mesothelioma not only occurs in people who are exposed the asbestos, but also to them who had been living in vicinity to asbestos manufacturing process or those staying in asbestos contaminated buildings. In Great Britain, an association was reported between Mesothelioma and people living within 1 kilometer of an asbestos factory. 
 
The risk of Mesothelioma is reported to be high in those cases where occupational exposure to asbestos is combined with cigarette smoking. Mesothelioma usually does not appear until after 5 to 10 years of exposure. Mesothelioma causes mechanical irritation and in the advanced cases, there may be symptoms of clubbing of fingers, and cardiac distress. The survival time of Mesothelioma patients is generally ranges from 12 months to 2 years of diagnosis and very few survive longer than 2 years. 
 
The following measures can be useful in preventing occurrences of Mesothelioma:
• Use of safer types of asbestos (chrysolite and amosite)
• Substitution of other insulators such as glass fiber, mineral wool, calcium silicate plastic foams
• Rigorous dust control
• Periodic examination of workers such as biological monitoring (clinical, X-ray, lung function) 
 
The government should take adequate steps and make appropriate legislation to stop or minimize the case of asbestos exposure Mesothelioma. If you or any one of your families or friends is suffering from Mesothelioma, you have the legal right to file lawsuits for getting compensation for the medical facilities, loss of income and pain. You can consult a qualified attorney for filing a Mesothelioma lawsuit for comensation.

Are asbestos fibers visible to the eye ?




by: Jeff Lakie
If you are in the construction business or employed by an industry that uses products containing asbestos, you may wonder “Are asbestos fibers visible to the eye”? Generally asbestos fibers are too small to be seen by the naked eye. Asbestos becomes dangerous when it has broken down into small fibers and is inhaled. It is nearly impossible to detect the presence of asbestos without taking the material to a lab for testing. A lab technician will put the material under a microscope to search for asbestos fibers. Asbestos does not cause an immediate reaction. It will not cause you to cough, sneeze, or your eyes to water. You cannot see, smell, or taste asbestos. If you skin becomes contaminated with asbestos it will not burn or itch. 
 
Asbestos related diseases have a very long latency period. This is the time frame from when you are first exposed to asbestos until you become ill. Most persons do not become ill for at least ten years after exposure and some not until over forty years later. Asbestosis, lung cancer, and mesothelioma are all asbestos related diseases. Asbestosis occurs when asbestos fibers enter the lungs. The body will naturally produce an acid to combat the fibers. However, this acid can cause scarring in the tissue of the lungs and in advanced stages breathing becomes more difficult and painful. Asbestosis was first documented in shipyard workers. Asbestos can also cause lung cancer. If a person smokes and is exposed to asbestos, they have a much greater chance of developing lung cancer. Mesothelioma is a type of cancer that has only been linked to asbestos exposure. It is a cancer of the cells that line the peritoneum (area surrounding the abdominal organs) and the pleura (area outside of the lungs and inside of the ribs). 
 
There is a lot of debate and controversy surrounding which types of asbestos is harmful. Some types of asbestos are thought to be more dangerous than others but all types of asbestos exposure should be avoided. Actinolite, amosite, anthophyllite, crocidolite, chrysotile (white asbestos), and tremolite are all types of asbestos. Chrysotile is the type of asbestos most commonly used in manufacturing products. 
 

Asbestos fibers are not visible to the eye. If you feel you may have been exposed to asbestos, the most common method for testing is a chest x-ray. The x-ray will not show the asbestos fibers but it can spot early signs of lung disease. There is no known cure for asbestos related diseases.
