I can't find a single article on Google that says eggs correlate with anything but a REDUCED risk of breast cancer. There are plenty of articles suggesting MEAT is an issue, so if you're going to be concerned, I'd focus your worry there rather than at eggs.
One article even suggested that choline intake in pregnancy reduced the breast cancer risk in the baby later in life. Choline is a component of egg yolks.
