safety concerns about sunscreen

Hi -I thought I'd pass this article along. It seems as though sunscreens may be estrogenic.
Here is the link:

thanks carol, but I am sure you understand that this article (a) is inconclusive and only calls for further study and (B) does not in any way suggest or imply that the estrogenic effects of these topical compounds could interact with estrogen receptors in breast cancer patients. Until there is good evidence that sunscreen causes breast cancer relapse in hormone positive women, I am going to choose to not subject myself to cancer-causing UVA and UVB rays....
