Glyphosate: No statistical risk found for any type of cancer at any site.
Glyphosate is the most commonly used--and most controversial--herbicide globally. Follow-up done between 1999-2015 in the Agricultural Health Study (AHS), a prospective cohort of licensed pesticide applicators living in North Carolina and Iowa, found no association between glyphosate and any solid or lymphoid malignancies, including non-hodgkin lymphoma. This data comes from the largest study of agricultural workers ever conducted.
PositiveTip: While one should always use due diligence in following exposure cautions, there does not appear to be any significant cancer risks to glyphosate use.
