According to the National Cancer Institute the risk of cancer from asbestos exposure as a very real and researched carcinogen is documented by the Environmental Protection Agency, the US Department of Health and Human Services and the International Agency for Research on Cancer. Individuals of any age that are exposed to asbestos may develop specific symptoms that are often linked to the development of lung cancer due to asbestos contact. Asbestos is most problematic in specific industries including but not limited to construction, refining and in shipbuilding and other types of building industries. Although the EPA, the Environmental Protection Agency, legally banned the use of asbestos in any new products as of 1989, however existing manufacturing and usage is still allowed provided the companies are following specific laws and standards for the use of asbestos. Currently over 3000 products sold or used in the United States still contain some form or type of asbestos.
