Causes and PreventionINDEX...HOME Good Sites Working with asbestos is the major risk factor for mesothelioma. A history of asbestos exposure at work is reported in about 70 percent to 80 percent of all cases. However, mesothelioma has been reported in some individuals without any known exposure to asbestos. Asbestos is the name of a group of minerals that occur naturally as masses of strong, flexible fibers that can be separated into thin threads and woven. Asbestos has been widely used in many industrial products, including cement, brake linings, roof shingles, flooring products, textiles, and insulation. If tiny asbestos particles float in the air, especially during the manufacturing process, they may be inhaled or swallowed, and can cause serious health problems. In addition to mesothelioma, exposure to asbestos increases the risk of lung cancer, asbestosis (a noncancerous, chronic lung ailment), and other cancers, such as those of the larynx and kidney. Smoking does not appear to increase the risk of mesothelioma. However, the combination of smoking and asbestos exposure significantly increases a person's risk of developing cancer of the air passageways in the lung. Since mesothelioma primarily caused by exposure to asbestos, the best way to prevent mesotheliomas is to avoid or limit your exposure to asbestos in homes, in public buildings, and at work. People who may be exposed to asbestos include reonvators, trades people, miners, factory workers, insulation manufacturers, railroad workers, ship builders, gas mask manufacturers, and construction workers, particularly those involved with insulation. If there is a possibility of on-the-job exposure, such as renovating old buildings, then you should use all protective equipment, work practices, and safety procedures designed for working around asbestos. If you live in an older home, there may be asbestos-containing insulation or other materials. An expert can check your home to determine if there is any asbestos and if it poses any risk of exposure. It is often more dangerous to remove the materials containing asbestos than to leave them alone. You may then decide to have the asbestos removed from your home. You should hire a qualified contractor to perform this job, to avoid contaminating your home further or causing any exposure to the workers. You should not attempt to remove asbestos-containing material yourself. |
