Mesothelioma Cancer - An Overview

By William Johnston

The cause of mesothelioma cancer:

Mesothelioma is a cancer caused by exposure to asbestos without sufficient protection over one's mouth and nose. Asbestos is a fibrous mineral which was discovered in the 1860s but not properly used until the 1930s. Asbestos was used hugely in construction due to its property of being fireproof even at high temperatures. It was not until the 1960s that it became clear that asbestos was causing a number of diseases. These diseases include mesothelioma, asbestosis and lung cancer.

Asbestos as the cause of mesothelioma:

When exposed to asbestos without sufficient protection, a person will inhale many tiny asbestos fibres that are suspended in the air. These will pass into the respiratory system and get most probably get lodged in the lining of the lungs. An accumulation of these fibres can cause the cells around it to become abnormal and this can lead to mesothelioma. Through the lymphatic system, asbestos fibres can become lodged in the lining of the abdomen or in the lining of the heart.

The suffering endured by patients of mesothelioma:

The symptoms of mesothelioma vary depending on what type of mesothelioma a patient has. However, there are several common symptoms of all types. These include chest pain, shortness of breath, coughing, coughing up blood, weight loss and loss of appetite. These symptoms usually take affect only when the mesothelioma cancer has fully matured and developed. Due to the fact that these symptoms are frequent for a number of more common diseases such as pneumonia, mesothelioma is very difficult to diagnose in its early stages.

The treatments available for mesothelioma:

As yet, all treatments for mesothelioma have a low success rate. The effectiveness of treatment depends largely on how aggressively and early the cancer is treated. If treated in its later stages when it has fully developed, it is extremely difficult, almost impossible to cure. Treatments include surgery which comes in two forms, aggressive surgery and palliative procedures, radiation therapy, chemotherapy and dual therapy which is a combination of all three main treatments combined. Dual therapy has shown the most promising signs so far as a curer for mesothelioma.

Mesothelioma research:

Research is being undertaken in numerous research labs all across the United States although so far no breakthroughs have been made. Many pharmaceutical companies are also endeavouring to find new drugs for chemotherapy. Researchers have recently predicted that a long awaited new treatment method for mesothelioma is on the way to being discovered.

Mesothelioma Cancer

By Rob Mellor

Mesothelioma is a rare type of cancer in the general population. However, in individuals that were exposed to asbestos, it is not as rare. There are experts that have speculated on other causes. There are incidences of Mesothelioma with no known asbestos exposure. Mesothelioma is not a lung cancer. Smoking does not cause it. It is a cancer of the mesothelial cells.

Causes of Mesothelioma
The only known, established cause of Mesothelioma is asbestos. The asbestos fibers are breathed in, travel through the lung and become lodged in the pleura, the thin, saran wrap-type membrane that lines that encases the lung. The pleura, produces a special lubricating fluid that facilitates the ability of the lungs to move inside the chest during breathing. The process of irritation from the infiltration of the asbestos fibers creates changes in the cells, which causes the Mesothelioma. This is known as pleural Mesothelioma. Less common is peritoneal Mesothelioma, which is a cancer of the membrane that encompasses the lining of the abdomen.

Symptoms of Mesothelioma
An individual with Mesothelioma experiences chest pain usually caused by a build-up of fluid in the pleural space called an effusion and shortness of breath. Since many doctors may not have expertise in the area of asbestos-related diseases, these symptoms are often believed, at first, to be attributable to other medical problems. A biopsy of the pleural tissue or fluid may reveal the cancer of the mesothelial cells and a proper diagnosis can thus be established. A history of the individual's occupational exposure shall be taken. Since there is no "safe" level of exposure to asbestos, even brief, low level exposures may be enough to cause Mesothelioma.

Occurrence of Mesothelioma
Mesothelioma is an aggressive cancer and its incidence is actually increasing day by day. There is presently no known cure for Mesothelioma. As the disease progresses, the cancerous cells harden the pleura and spread. As time passes, breathing, sleeping and eating become more difficult and eventually it becomes increasingly more challenging for the victim to engage in normal activities and enjoy life.

Treatments of Mesothelioma
A number of treatments have been established to help contain the spread of the disease and reduce the pain associated with it. Chemotherapy, radiation and radical surgery to remove the lung and pleura are among the options that have been explored by the treating physician.

Prevention is better than Cure
Mesothelioma is a preventable disease. Many of the corporations that manufacture and make profit from the sale of asbestos-containing products are aware of the hazards of asbestos. Alternative fibers are available that could be used instead of asbestos. But asbestos is cheap, and available, and is a good filler and binder.

To Sum up
The varied and non-specific symptoms associated with Mesothelioma, can delay detection and diagnosis The cancer has a very long latency period, which means that it could be thirty years or more before the person even realizes that they have contracted the cancer .The onset of symptoms can take up to fifty years or more in some cases, but once the symptoms have manifested the lifespan of the person can be as short as several months. So, if you or a loved one is experiencing any of the above symptoms, consult your doctor right away. Make sure that your physician is aware of any previous asbestos exposure, and occupational risk factors.
