(Dietary) copper regulates receptors. http://press.endocrine.org/doi/full/10.1...002-221054 "Discussion" section. too high levels cause estrogen excess, and can cause problems during pregnancy.

(Dietary) chromium decreases ER-alpha proteins (in cancer cells but believed to do this in healthy cells too), decreasing sensitivity.(lacking source)

"breast cancer patients have abnormal levels of copper (Cu), Zn, Se, and Cd" (Copper, Zinc, Selenium, Cadmium) "here is also some evidence for an inverse association between Zn and breast cancer, while there is no association between exposure to Se and the risk of breast, colorectal, and stomach cancer and between Zn and the risk to develop prostate cancer [12]. Nevertheless, positive associations of breast cancer with Zn, iron, and calcium, but little association with Se, have been reported in [17]." http://www.ncbi.nlm.nih.gov/pmc/articles/PMC3143443/

Small amounts of chromium and copper found in food are essential trace nutrients. Excess of dietary estrogenic metals is carcinogenic. Other estrogenic metals are carinogenic. http://www.ncbi.nlm.nih.gov/pmc/articles/PMC3671233/

Calcium is an exception, as it is linked to reduced risk of breast cancer, http://www.eurekalert.org/pub_releases/2...041210.php.

Great post lovely, thanks!

I was looking into info regarding mineral toxicity testing and came across these articles a couple of weeks ago.

What do you have on mineral toxicity testing?
