Literature data has indicated that pesticides may stimulate cancer cells proliferation through different mechanisms, e.g., glyphosate stimulates human breast cancer cells growth through estrogen receptors pathways, diuron acts in a tissue-specific manner and ROS play a role in its toxicity, and bifenox and dichlobenil exhibit enhancing effects on oxidative stress, simultaneously stimulating cancer cell proliferation and inhibiting apoptosis [17,18,19]. The gene discussed is ESR1; the disease is breast carcinoma.
