Casein often gets a bad rap as a carcinogen however I could never find a source that was anything other than The China Study. Chris Masterjohn pokes some pretty hefty holes in the casein studies of Dr Campbell so his research on his own doesn't really make me worry too much. However, is there a larger body of research that I should know about?

I haven't looked into it that deeply and certainly not as deeply as CM.
That said, I'm aware of at least two other potential problems with casein (i.e., problems that I don't think CC mentions).
One other concern is that it can also cause food allergies that may, in some circumstances, be able to trigger autoimmune processes.
Another related (and speculative) concern (championed as far as I know by Peter at hyperlipid) is that casein may be a problem for people on PPIs, since without stomach acid, ingested casein may disrupt tight junctions in the gut... Pure speculation, but possible...
