Asbestos, despite it causing cancer, primarily lung cancer, it is still used worldwide though to a lesser extent.
According to Wikipedia, asbestos is a naturally occurring silicate mineral with long, thin fibrous crystals. The word asbestos is derived from a Greek adjective meaning inextinguishable. The Greeks termed asbestos the miracle mineral because of its soft and pliant properties, as well as its ability to withstand heat.
Asbestos is toxic. The inhalation of asbestos fibers can cause serious illnesses, including malignant mesothelioma, lung cancer, and asbestosis (also called pneumoconiosis). Since the mid 1980s, many uses of asbestos have been banned in several countries.
Should one be unfortunate enough to be stricken with cancer of the lungs, called mesothelioma, there are Mesothelioma lawyers who are well-versed in such cases and would be able to advise on legal options, etc.
