cancer's relation to household chemicals

According to the Toronto Indoor Air Conference of 1990, [...] as a result of a higher rate of exposure to toxic chemicals in common household products, women who are stay-at-home moms have a 54% higher death rate from cancer than those who work outside the home.  Unless, of course, their work outside of the home is as a low wage hotel maid, waitress, or housecleaner, where their daily exposure to highly toxic chemicals is even greater.
