There are links to this story also in the news forum, but I wanted to include it here with a personal observation. When you purchase vitamins, make sure to look at the list of ingredients - it isn't just the vitamin you are getting. I have seen soy listed as an ingredient on vitamin bottles and make a point to avoid it. My interpretation of this article is that the women who got bc may have been getting regular doses of soy they were not aware of.
Hopeful
