The biggest concern I have regarding future breast cancer rates is in relation to some common behaviors seen in the 20 and 30 year olds.
The Bermuda Triangle of risk factors are being on birth control pills, drinking alcohol and eating grilled meats. These are common behaviors of college and graduate school women.
Birth control pills are 90% of the time estrogenic and suppress the cycle. This allows women to go all month and in many cases now, a third of the year without ample progesterone. Breast tissue needs a balance of estrogen to progesterone, in fact our brains need progesterone for optimal functioning.
Alcohol unbinds estrogen from something called SBG, or sex binding globulin. Unbound estrogen is more active.
