Asbestos is a common material used in building construction and insulation prior to the 1980s. Though having asbestos in itself is not necessarily dangerous, it becomes hazardous if fibers of the material become airborne and are inhaled. Once any person inhales the fibers present in the air, they become lodged in the lungs which leads to lung cancer, mesothelioma, and other lung diseases. Asbestos testing is, therefore, an important process to ensure that you are not being exposed to harmful asbestos fibers.
