Syngenta’s own studies (1994) show that, if you give rats atrazine, there is an increase in breast cancer and mammary cancer . The mechanism for prostate and breast cancer is the following. Adrenal cells normalize aromatase and estrogen production to one, but if you give these human cells atrazine they express aromatase and start making estrogen. Like we have shown in fish and amphibians —and just like they’ve shown in
reptiles, just like they’ve shown in rats— lo and behold, human cells respond the same way.
