ESTROGEN IMBALANCE

Hi Folks,
This is amazing, but true.  I learned that all female reproductive cancers, breast, cervical,uterine, ovarian, endometrial, are "fueled" by estrogen imbalance. This is easily verified by searching the internet. A simple blood test would show if the estrogen is out of balance. I called my Kaiser advice nurse and asked why this blood test wasn't offered as routine screening. Though she didn't want to answer, she finally said that if the blood test showed an imbalance, it would put markers in the woman's medical record. The insurance companies periodically review the records and if they saw the marker, they would cancel their insurance with that woman. The advice nurse added that Kaiser wouldn't do that. But neither do they offer it as routine screening.
There is "no" known cause for estrogen imbalance. This is, also, easily verified by searching the internet. Yet there are many maladies that were cured or prevented by simple observation of non-professional people; two examples are the English sailors knew that limes prevented scurvy about a hundred years before it was accepted as true by England's medical establishment and it was know that the bubonic plague happened generally in the cities and the people living in the country weren't nearly as susceptible. It would certainly be worthwhile for a woman to consider her environment; since it is a reproductive organ problem, could there be a reproductive activity that she is involved with that might be the causal factor? It is known that certain lifestyles that have greater problems of this nature.
