Several studies have actually looked at the life expectancy in women taking estrogen versus those that don't take estrogen. In about all situations, the life expectancy is increased if you take estrogen. This is mainly because of the lower risk of heart attacks when you take estrogen. The prevention of osteoporosis can potentially save lives. One study showed that taking estrogen after menopause was associated with an increased life expectancy of up to 2.3 years.
Heart attacks are the leading cause of death overall in females.
The annual death rate from heart disease in females in the United States is 359,000. On the other hand if you have a markedly positive family history of breast cancer then the decision whether or not to take estrogen becomes more difficult. There are three ways to take estrogen replacement therapy. Take Premarin .625 mg. Provera 10 mg.
