Author Description

Excerpt from A History of Cancer Control in the United States, 1946-1971, Vol. 1: A History of Scientific and Technical Advances in Cancer Control Occupational carcinogenesis has a two century history dating back to the observations of Dr. Percival Pott, a London surgeon, who in 1775 first noted the high rate of scrotal cancer among young boys who toiled as chimney sweeps. (l) Pott's findings, which were really coincidental with the onset of the Industrial Revolution, were to be followed by others. In 1822, dr..a. Paris, another English.physician, noted the high incidence of skin cancer among workers exposed to inorganic arsenic. (2) By the early 19005, the cancer - causing hazards of certain dyestuffs, cutting oils, and radioactive substances were also becoming evident. (3) For the most part, the pre-twentieth century discoveries in occupational carcinogenesis took place in western Europe where industrialization generally had proceeded further than in the United States.
