I just read this too. Your theory is interesting, Hopeful. Generally though the soy in the MVI is not a component containing isoflavones which is the biggest concern for breast cancer although some MVI and now calcium supplements contains genistein. It would be interesting to see the nutrient breakdown of the MVI used in the study. I wonder about folic acid. There has been recent discussion on over-supplementation of folic acid and colon cancer. It is just a thought. I will be following this as I am sure many of you will also do.

Here is the PubMed link.

Also, I note that the study used self-administered questionnaires which may lead to some inaccuracies in reporting lifestyle habits. My overall feeling on this study is that there is not enough solid information to link MVI and breast ca. As indicated in the study, further investigation is needed. I guess it gives us another reason to focus on a healthy, well-balanced diet.
