The physical properties that give asbestos its resistance to heat and decay are linked with several adverse human health effects.
Asbestos tends to break into a dust of microscopic fibers.
Because of their size and shape, these tiny fibers can remain suspended in the air for long periods of time and can easily penetrate body tissues when inhaled. Because of their durability, these fibers can remain in the body for many years. Exposure to asbestos can cause mesothelioma, lung cancer, asbestosis, pleural disease and other cancers. For a very general overview of these diseases, read below. It is important to note that not all people exposed to asbestos will develop an asbestos-related disease.
