I wonder how long it will take before we'll see more studies on dairy and IGF-1 and how they affect cancer. I seriously doubt that it's a coincidence that the Nordic countries have some of the highest cancer rates in the world, since they also drink the most milk. Or that the people with the Laron syndrome are resistant to cancer, since (if I remember correctly) they have some sort of defect in their IGF-1 receptors.

T. Colin Campbell talks a bit about this in his books (China Study etc.). I think he's correct that there is some sort of taboo against questioning dairy and protein.

Edit: I should probably mention that IGF-1 is a growth hormone. Cow's milk contains a lot of IGF-1. You know, those calves are pretty small when they are born, but are supposed to grow into full-size cows. Both humans and cows have receptors for the very same IGF-1.
