She presents with stage 2 estrogen receptor positive breast cancer.

And what's interesting about BPA is that it's such a potent estrogen that it was actually once considered for use as a synthetic estrogen in hormone placement therapy.

So we're dosing our babies, our newborns, our infants, with a synthetic estrogen.

I would even say that with Viagra, estrogen replacement, hip replacements and the incredibly interesting women

It's a material hardener and synthetic estrogen that's found in the lining of canned foods and some plastics.

And I have concocted a questionnaire to see to what degree you express dopamine, serotonin, estrogen and testosterone.

But what atrazine does is it turns on an enzyme, the machinery if you will, aromatase, that converts testosterone into estrogen.

Because it turns out that the number one cancer in women, breast cancer, is regulated by estrogen and by this enzyme aromatase.

Women's ability to find the right word rapidly, basic articulation goes up in the middle of the menstrual cycle, when estrogen levels peak.

I would even say that with Viagra, estrogen replacement, hip replacements and the incredibly interesting women women have never been as interesting as they are now.

PJC So speaking of estrogen, one of the other compounds that Tyrone talks about in the film is something called bisphenol A, BPA, which has been in the news recently.

And what was remarkable about it was in the past when we think of chemical messengers within the body, we thought of complicated things like estrogen and insulin, or nerve transmission.

So when you develop a cancerous cell in your breast, aromatase converts androgens into estrogens, and that estrogen turns on or promotes the growth of that cancer so that it turns into a tumor and spreads.

It's interesting, because it was six years ago when I was pregnant with my first child that I discovered that the most commonly used preservative in baby care products mimics estrogen when it gets into the human body.

In fact, this aromatase is so important in breast cancer that the latest treatment for breast cancer is a chemical called letrozole, which blocks aromatase, blocks estrogen, so that if you developed a mutated cell, it doesn't grow into a tumor.

And this is not just philosophical, it's already known, that chemicals like diethylstilbestrol and estrogen, PCBs, DDT cross the placenta and effectively determine the likelihood of developing breast cancer and obesity and diabetes already when the baby's in the womb.

Now what's interesting is, of course, that we're still using 80 million pounds of atrazine, the number one contaminant in drinking water, that does the opposite turns on aromatase, increases estrogen and promotes tumors in rats and is associated with tumors, breast cancer, in humans.
