Research finds 485 chemicals in US pesticide products linked to breast cancer

Researchers have identified 485 chemicals in US pesticide products linked to breast cancer, found not only in crop pesticides but also in lice treatments, lawn fertilizers, and flea treatments. The study highlights regulatory gaps, as the EPA evaluates individual ingredients rather than entire formulas or cumulative exposure to multiple pesticides. This finding is particularly concerning as early onset breast cancer rates are rising globally, with incidence increasing 1% annually and 1.4% annually in women under 50.
