One of the more interesting pieces of scientific study is the Women’s Health Initiative Study. In its most recent incarnation, after some 11-12 years of study, it now shows that estrogen-progestin therapy is associated with diagnosis of cancer of the breast not only well behaved and well differentiated tumors but also poor outcomes. This is different from other data previously shown by previous observational studies. It would seem to be confounding. On the surface it would appear that previous cause and effect is not what we thought, but is something else altogether. This is all very interesting, as there are many ways to interpret this information.
The way in which this will be interpreted by the medical scientific community is that we did not understand it previously, as well as we thought, and now we understand it better. They will say that, the better that we understand it, there is now a definite association with breast cancer as far as the intake of estrogen and progesterone is concerned. This was previously thought to be only related to the estrogen receptor dependent breast cancer tumors. In fact previous studies have shown no link between estrogen and breast cancers.
Despite the lack of evidence showing any relationship between breast cancer and estrogen, nevertheless women have become scared about a relationship. Additionally, evidence was that in the subset of women who developed breast cancer it was related to previously existing tumor, as at five years, when that arm of the study was discontinued, it was too short a time for development of a palpable tumor from scratch. Despite this, most gynecologists in response to their patients behaved as if it was caused by the estrogen-progesterone combination, rather than it being a situation where tumor growth was enhanced. This, latter was in agreement with early birth control pill data from over forty to fifty years ago.
I am not sure about this commentary..although there have been plenty of articles going back and forth on the estrogen/progesterone breast cancer /HRT issue.. Although I get changing the perception of reality – why is it women who are always asked “how are you making this up?”, “Or its all in your head….”, this is what is most troublesome to me.
It seems to me that it is time for us to wake up and realize that this reality women are trying to create – is the real reality….and our bodies and natural cycles are not a disease, nor an inconvenience subject to medical intevention.
