I just saw on the news that in Norway there is a study that says there is an increase in people who take folic acid with vitamins B's. I'm wondering since I remember hearing in the past that women who have had children are more likely to get cancer. It might have been those who breast feed, but I can't remember for sure. I just wondered though....women who breast feed were probably on folic acid and a lot of times they are with the B vitamins. I hope they can look into this to see if this could be part of the reason for some.
