Could RU-486 Prevent Breast Cancer?

Early research is promising, reports Jessica at Feministing, who notes that:

"No one is suggesting women use the abortion pill that way. But [a] provocative experiment helped illustrate how the notorious breast cancer gene BRCA1 does its dirty work, by spurring a hormone called progesterone that RU-486 happens to block.

"If researchers could create a safer hormone blocker, it might offer a long-awaited alternative for women with the bad gene. They have few good options today to prevent breast cancer."
