Week 10 - Child Cancer Risk

I wonder how much the chemical splay in the role of these children getting cancer. I understand that their lack of exposure to germs makes their immune system weaker in the long run, but the chemicals used to clean their homes must be equally damaging. It' easy to understand how poisonous those chemicals are just from getting a whiff of them. In the past, poisonous man made chemicals have been proven to cause caner and that seems a more likely cause than germs that others seem to be able to fend off.
