I have harped on this a lot, but here it goes again. We have to be more careful about the things we put in/on our bodies. Just because one product cannot kill you with trace amounts of carcinogens (cancer-causing ingredients), does not mean that all the products you use on a daily basis cannot cumulatively give you cancer. Yikes. Check your household products on the Skin Deep database on the Environmental Working Group website linked on my sidebar.
Also, read this blog post which basically sums up what I think about these issues. I know there is nothing I can do about the past, but I sure get frustrated that I did not know this stuff when M was a baby. Grrrrrr.
