What is the connection between estrogen and cancer?
There is now no question that estrogen can be linked to certain cancers. For instance, estrogen has been shown to contribute as much as 30% of an increase in breast cancer. It has also been shown that as many as two thirds of women taking estrogen can develop uterine lining abnormalities. Also, evidence is showing that estrogen use can be associated with cancer of the bladder, pancreas, cervix, endometrium and the brain.
