Glyphosate use and cancer incidence in the Agricultural Health Study
no association was apparent between glyphosate and any solid tumors or lymphoid malignancies overall, including NHL and its subtypes. There was some evidence of increased risk of AML among the highest exposed group that requires confirmation.
A prospective cohort of 54,251 licensed pesticide applicators, 82.8 percent of whom used glyphosate, with cancer incidence followed through 2012–2013. Glyphosate was not significantly associated with cancer at any site in unlagged analyses. In the highest exposure quartile the risk of acute myeloid leukemia was 2.44 times that of never users (95% CI 0.94–6.32); with a 20-year lag the highest tertile reached 2.04 (1.05–3.97). Critics note the study's imputation of missing exposure data and a reference group that included low-exposure users.
