Asbestosis, Mesothelioma, Lung Cancer ? Asbestos ...

Asbestos has many appealing qualities for builders. It is strong, flexible and corrosion resistant. It is also burn resistant and a good insulator. There are not many substances with these qualities and may explain why it was so widely used. It becomes hazardous when asbestos containing materials are disturbed or damaged. Asbestos is made up of microscopic bundles of fibers. When the materials become disturbed or damaged, these fibers separate and may become airborne. These fibers may get into the lungs and that may lead to serious and even fatal diseases. Some of these diseases include:

Statistics show that of all the ethnic groups in the world, the incidence of cancer in the lungs in African Americans is the highest. The reason often cited is that it has also been shown that African Americans smoke more than other ethnic groups.

You may not be aware but this cancer is considered to be one of the most life-threatening kinds of cancer. Cancer statistics show that the five year survival rate of breast cancer patients is 87%, while that of colon cancer patients is 62%. Similarly, there is a 92% five year survival rate for prostate cancer patients. You will be shocked to learn that the five year survival rate of lung cancer patients is as low as 15%.

Photodynamic therapy is as unique as it is hard to explain. There are certain chemicals that are very light sensitive. The body can absorb some of these chemicals into cells and then expel them. Cancerous cells, however, cannot expel the chemicals. A patient is given a dose and then the cells are exposed to a laser light. The chemicals kick out an active form of oxygen that destroys the cancerous cells. There is a downside, however. The patient becomes very light sensitive and often must stay out of the light for as long as six weeks.

Anti-angiogenesis treatment is another interesting area of treatment. It works by attacking the tumors created by Mesothelioma. It does this by eliminating the ability of the tumors to create blood vessels. Without such vessels, the tumors cannot get blood and cannot grow. Drugs such as Cisplatin, Pemetrexed and Bevacizumab are in clinical trials to determine if they can be used on Mesothelioma tumors.

There is a nine times higher probability for someone who smoked previously to die from lung cancer, than there is for someone who has never smoked. Also, there is a twenty-three times higher probability of a lung cancer patient who continues smoking to die, than there is for someone who has quit smoking
