The available literature data report that pesticides can stimulate the proliferation of cancer cells using various mechanisms, e.g., glyphosate acts as an EDC compound stimulating the growth of breast cancer by activating estrogen receptor pathways (both ER-α and ER-β), ROS mediate in the induction of diuron toxicity, while herbicides such as bifenox and dichlobenil stimulate oxidative stress, while increasing the proliferation of cancer cells and inhibiting apoptosis [4,46,47]. The gene discussed is ESR2; the disease is breast cancer.
