Interesting. It is also good to note, too, that there has been some debate as to whether casein (a milk protein) is implicated in aggravating cancer cells. The same arguments have been made about animal proteins in general. Then again, anything that encourages the division of healthy cells (a glut of calories, protein) is apt to encourage the same in cancer cells. And that may be the issue; we all produce abnormal cells at some rate, but a healthy immune system (NK cells in particular) can remove small numbers of them, keeping them in check. With advancing age, the number of NK cells and other immune activity is severely decreased, which decreases the body's ability to keep up with the advancing rate of abnormal cell line genesis.
The paper does point out that, since these hormones are fat-soluble, their concentration in skim products is still low.
