Cancer – an unbeatable undertaker: A myth or reality?
Death is indeed inevitable. It can be reach us through several ways and modes. Sometimes it comes in the form of accidents and many a times in the form of diseases. Cancer is acclaimed to be the most fatal and malignant of all the diseases.
Several researches have been conducted worldwide to inquire into the real cause of cancer. The cause as reported by these studies varies. Cancer is sometimes the result of excessive cell division which enhances an uncontrolled growth of cells. The intrusion of tissues into adjacent tissues, a process known as invasion also causes cancer. Metastasis enables cancer to be spread throughout the body with the aid of the body fluids like lymph and blood. The abnormalities found in the genetic material can also affect adversely, causing cancer. The abnormalities are attributable to various factors like exposure to tobacco smoke, harmful chemicals and other infectious agents.
Cancer does not confine itself to some particular organs. It is proven that cancer can affect all the parts of the human body and can cause much damage to the body as such. The most commonly affected part is the lung. Lung cancer accounts to be the cause of a good majority of cancer deaths. It is mainly due to the uncontrolled growth of the cells in the lung. The major cause of lung cancer, as reported by the researchers, is the continuous exposure to tobacco smoke. Smoking as well being exposed to second hand smoke can result in cancer.
Mesothelioma or asbestos cancer is one among the most deadly forms of cancers. The cause of this cancer is said to be the prolonged exposure to asbestos, a fibrous mineral. The microscopic fibers of asbestos enter the mesothelial cells during this period of exposure. The mesothelial cells line most of the internal organs as well as the body cavities.
Asbestos cancer is commonly found among workforce who work in conditions where they are exposed to asbestos dust and fibers. These fibers tend to cover most of the internal organs, thereby worsening the condition. This disease can also be acquired through passive ways like washing the clothes of a person who works with asbestos.
Mesothelioma can be diagnosed by many modern techniques like X-Ray, CT scan, and MRI scan. The sought after treatment methods include surgery, chemotherapy, radiotherapy, gene therapy, immunotherapy and so on.
