Regulatory agencies around the world have evaluated the safety of herbicides. The International Agency for Research on Cancer (IARC), a part of the World Health Organization, classified glyphosate as "probably carcinogenic to humans" (Group 2A) in 2015. In contrast, the Environmental Protection Agency (EPA) in the United States has stated that glyphosate is "not likely to be carcinogenic to humans" based on their review of the evidence. These differing conclusions highlight the complexity and ongoing debate surrounding herbicides and cancer.
