In Illinois, cancer and pesticide rates typically rise together

Three-fourths of Illinois counties have higher-than-average cancer rates and 25% more pesticide use than other state counties. Nationally, 60% of counties with the highest pesticide use also have elevated cancer rates, with similar patterns in Missouri, Iowa, and North Dakota. A 2024 study linked pesticides to cancer risks comparable to smoking, and Illinois lawmakers have proposed but failed to pass regulations on agrichemical use.
