Hi Susan

I can't say I have heard of this study. However, whenever I read a study as the one you mention I look at who it is coming from, how they performed researched, etc. to check for bias or reliability.
Most of my friends as well as myself have been wearing makeup since sixth or seventh grade and as far as I know, have never been diagnosed with cancer from makeup. There are hundreds of studies trying to correlate two variables that could be exmplained by other means...for example, our air quality is not the best. So due to a combination of environmental factors, perhaps teens are having issues with puberty and cancer but I wouldn't think is it just makeup acting as a cause.
There are some chemicals to avoid. Gather Inc. has a list of chemicals you would want to avoid in your makeup
that could be toxic. A website that may be of interest to you is the Campaign for Safe Cosmetics:
there is great information! Thanks for the comment!
