Pesticides that mimic estrogen can increase breast cancer risk. While estrogen is important for female reproduction, it can trigger or fuel breast cancer. Some pesticides accumulate in fat and mimic estrogen, stimulating "bad estrogen" production. To reduce exposure, women can eat organic food, avoid using pesticides, and breastfeed to help remove toxins from their bodies, though breast milk is now highly contaminated. People should pressure governments to better regulate and re-evaluate pesticides for their potential health risks.
