Mesothelioma Asbestos And Its Deadly Nature

By Heidi Wingrain

Our vital organs are sheathed in a single layer of compacted cuboidal cells. This layer, called mesothelium lines the serous cavities of our body. The cells of this covering become cancerous when particles of mesothelioma asbestos get deposited in it. The infection slowly retards the normal functioning of nearby organs thereby resulting in death. Statistics prove that almost ninety percent of all mesothelioma cases occur due to asbestos exposure only.

Asbestos is a naturally occurring mineral that is put to extensive industrial use. Its flexible but strong fibers can be converted into thin threads. It is widely used in making cement, roof shingles, textiles, insulation etc. During the manufacturing period, thin fibers float in the air and get inhaled or swallowed and many of these particles reach the mesothelium. The fibers of this material have the capability to change the functions of macrophages and thereby create suitable conditions for mesothelioma development. Mesothelioma asbestos retards the functioning of our immune system by deactivating tumor suppressor genes and activating oncogenes, proto-oncogenes, error prone DNA repair enzymes and telomerase and prevents apoptosis.

Mesothelioma risks are greater among people residing near asbestos mines. The most risk prone category is the workers working in the factories where asbestos is used as raw material. The risk factor can be reduced greatly by wearing protective gear while dealing with asbestos.

Family members of people who work in asbestos filled atmosphere may also contract the cancer through the particles carried by the worker's clothes and hair. Showering and changing cloths after work are essential to counter this. Some building materials, especially those used for insulation contain asbestos, which may endanger the lives of the inhabitants.

Mesothelioma symptoms are visible only many years after the exposure to asbestos particles. By that time it will be too late. An early diagnosis along with proper treatment has increased the lifespan of many affected people. Traditional methods like surgery, chemotherapy, radiation and new methods of treatment like gene therapy are used to fight against this malady. But it is always better to use preventive measures than going for a cure. Using protective gadgets will help while handling mesothelioma asbestos.
