The possibility that occupational exposure to asbestos (1332214) could be a risk for the development of colorectal cancer was investigated. The study population consisted of case and control subjects ever employed in so called exposed trades (insulation workers, sheetmetal workers, boilermakers, pipefitters, and plumbers). These were compared with case and control subjects solely employed in unexposed occupations that are not expected to result in significant asbestos exposure. The study included 261 cases of incident cancers of the colon and rectum and 183 control subjects. The findings showed a diminished risk of cancers of the colon and rectum among men employed in trades with known asbestos exposure. The authors note that their findings differ from those of previous studies which showed elevated risk. The authors do stress that their study is limited due to small numbers of exposed cases, unavailable data on potential confounders, and lack of precise exposure information.
