"Women working in certain types of jobs — mainly agriculture and industrial settings — appear to have about double the risk of developing breast cancer as women who do other kinds of work, a new Canadian study says.
The work suggests the increased risk is likely the result of exposures to chemicals used in some factory-type jobs and second-hand smoke in entertainment sector jobs, plus shift-work across a variety of these job sectors."
