ENVIRONMENT AND OCCUPATION
(Back to Top)Overview:
Environmental
causes probably account for well over half of all cancer cases. Most
environmental risks are determined by lifestyle choices (smoking, diet, etc.), while the
rest arise in community and workplace settings. The degree of cancer hazard posed
by these voluntary and involuntary risks depends on the concentration or
intensity of the carcinogen and the exposure dose a person received. In situations
where high levels of carcinogens are present and where exposures are
extensive, significant hazards may exist, but where concentrations are low and
exposures limited, hazards are often negligible. However, when low-dose exposures
are widespread, they can represent significant public health hazards (for
example, secondhand tobacco smoke). Strong regulatory control and constant attention
to safe occupational practices are required to minimize the workplace
potential for exposure to high-dose carcinogens. Chemical
