Since 1993, many American cows are given Bovine Growth Hormone to increase their milk production. This hormone also naturally stimulates liver production of "insulin-like growth factor 1" (IGF1), part of which will end up in the milk. Elevated levels of IGF1 in human blood has been linked to increased rates of breast, colon, and prostate cancer by stimulating their growth. Milk from those "Monsanto cows" is banned in the EU, in Canada, Australia, New Zealand, and Japan. Recently the two largest supermarkets in the United States--Wal-Mart, and Kroger--announced that they are "on a nationwide search for rBGH-free milk".

If something like that was fed to the cow and can be excreted in milk, then it can.
