Unfortunately there is no benefit to not taking estrogen. I see women weekly and sometimes daily whose lives have been destroyed by lack of estrogen. Women who never take estrogen develop just as much breast cancer as women who take estrogen. Not taking estrogen delays the diagnosis for 1 to 2 years. This makes the prognosis worse. Women should start estrogen at menopause and continue it lifelong. Without estrogen women age fast. Women not on estrogen eventually begin to shrink, and then shrink progressively and continually. This does not need to happen. Within 2 years of starting estrogen women in their 60s, 70s, 80s and 90s stop losing height and do not shrink for at least the next 5 years. Women should not ask for estrogen, they should demand it!
