§5208. Asbestos, Appendix H
I. Route of Entry:
Clinical evidence of the
adverse effects associated with exposure to asbestos is present in the form of
several well-conducted epidemiological studies of occupationally exposed
workers, family contacts of workers, and persons living near asbestos mines.
These studies have shown a definite association between exposure to asbestos and
an increased incidence of lung cancer, pleural and peritoneal mesothelioma,
gastrointestinal cancer, and asbestosis. The latter is a disabling fibrotic lung
disease that is caused only by exposure to asbestos. Exposure to asbestos has
also been associated with an increased incidence of esophageal, kidney,
laryngeal, pharyngeal, and buccal cavity cancers. As with other known chronic
occupational diseases, disease associated with asbestos generally appears about
20 years following the first occurrence of exposure. There are no known acute
effects associated with exposure to asbestos.
Epidemiological studies indicate that the risk of lung cancer among exposed
workers who smoke cigarettes is greatly increased over the risk of lung cancer
among non-exposed smokers or exposed nonsmokers. These studies suggest that
cessation of smoking will reduce the risk of lung cancer for a person exposed to
asbestos but will not reduce it to the same level of risk as that existing for
an exposed worker who has never smoked.
