I don’t know if this stuff is the real culprit in breast cancer, but something sure is. There seems to be an epidemic of it. Out of 150 women in our office, a dozen or so have breast cancer. That’s a fairly high percentage. A lovely young mother in my neighborhood is dying from breast cancer. Three cousins have had it (that branch of the family has a genetic predisposition). Looking at death records from the nineteenth century, breast cancer was not often listed as a cause or contribution to death, and the medical literature back then doesn’t speak of it often.
I think it has to do with birth control pills.
I don't doubt that your statement is accurate, but there are other possible explanations. For example, look at the higher rate of women dying in childbirth-- many women did not live long enough to develop breast cancer. One possible cause of the increase in cancer is simply that it typically develops later in life; longer life spans now mean that many people are living long enough to develop it. Many nineteenth century women who might have developed breast cancer later in life instead died from complications in childbirth, diphtheria, cholera, typhoid....
I recently met a woman whose 28 year old sister had just been diagnosed with breast cancer that she said was directly linkrd to this chemical. I don’t know how they knew that, but this lady’s Dad was a doctor, and she was under very good care.
