cancer's relation to household chemicals

From this article:

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.

Oh my.

Yikes! That also makes me worry for the young children they are staying home with.
