Statistics don't count in medicine if you are the one who gets the disease.
The reality is with this kind of thing we're really off into rounding errors. To the extent you can affect your odds of getting cancer, the extent to which you do the things your mother told you to do (don't smoke, don't drink, eat your vegetables, and don't get too fat) swamps your cancer risk from environmental sources.
I do think that regulations mandating the use of new chemicals without decades of health testing is pretty irresponsible though.
