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.

This is why a little information is dangerous. IGF-1 is not a growth hormone. It is produced in the liver and other organs stimulated by growth hormone. IGF-1 cannot be absorbed orally, so even if as you say milk contains tons of IGF-1 (which I don't believe is true either but don't care to prove otherwise). You could drink it all you want but it's broken down in digestion and not absorbed. Also IGF-1 does not cause cancer in itself, though it may be implicated. It causes undifferentiated cell growth and proliferation, and can prevent cell death. So if you have unhealthy cells that can be cancerous, those will also be grown and proliferated. By reducing IGF-1 that can cause a decrease in cancer in the sense that you've now slowed down ALL cell proliferation, good and bad.

Also I wonder if type of dairy (fermented/processed/etc) serve as additional confounders. PS do not forget sunlight/vitamin D levels if speaking about Nordic countries specifically not just dairy. Also a known cancer risk factor.
