Hormone Mimicking Properties of Glyphosate Weed Killer and Related Compounds Increase Breast Cancer Risk - Beyond Pesticides Daily News Blog (Beyond Pesticides, November 25, 2022) A study published in Chemosphere adds to the growing body of research demonstrating the endocrine (hormone) disrupting effects of glyphosate play in breast cancer development. Exposure to the herbicide glyphosate and other glyphosate-based herbicides (GBHs) at high concentrations mimics the estrogen-like cellular effects of 17β-estradiol (E2), altering binding activity to estrogen receptor α (ERα) sites, thus causing fundamental changes in breast cancer cell proliferation (abundance).  Glyphosate is the most commonly used active ingredient worldwide, appearing in many herbicide formulas, not just Bayer’s (formerly Monsanto) Roundup®. The use of this chemical has been increasing since the inception of crops genetically modified to tolerate glyphosate over two decades ago. The toxic herbicide readily contaminates the ecosystem with residues pervasive in food and water commodities. In addition to this study, literature proves time and time again that glyphosate has an association with cancer development, as well as human, biotic, and ecosystem harm. Therefore, advocates point to the need for national policies to reassess hazards associated with disease development and diagnosis upon exposure to chemical pollutants. The researchers note, “The results obtained in this study are of toxicological relevance since they indicate that glyphosate could be a potential endocrine disruptor in the mammalian system. Additionally, […]
