What do risk factors for breast cancer such as early menarche, late menopause, & nullipara have in common?

In brief: Hormone

Longer exposure to higher levels of estrogen hormones is suggested, but these statistical findings are a measurement of increased risks.
The statistics are not meant to tell us why things happen, they only measure what is seen in the us population. See gail risk model measurements.

It seems like cycles might be the problem for some reason since steady levels of high hormones (like pregnant women) actually reduce risk.
