There is limited evidence that human cancer risk might increase as a result of occupational exposure to large amounts of glyphosate, such as agricultural work, but no good evidence of such a risk from home use, such as in domestic gardening.<ref name=cruk>{{cite web |publisher=Cancer Research UK |title=Food Controversies&mdash;Pesticides and organic foods |url=https://www.cancerresearchuk.org/about-cancer/causes-of-cancer/diet-and-cancer/food-controversies#food_controversies4 |date=2016 |archive-url=https://web.archive.org/web/20170206193833/https://www.cancerresearchuk.org/about-cancer/causes-of-cancer/diet-and-cancer/food-controversies#food_controversies4 |access-date=2017-11-28 |archive-date=2017-02-06 }}</ref> The consensus among national pesticide regulatory agencies and scientific organizations is that labeled uses of glyphosate have demonstrated no evidence of human [[carcinogen]]icity.<ref name=Tarazona>{{cite journal

In 1986, glyphosate was initially classified as Group C: "Possible Human Carcinogen", but later recommended as Group D: "Not Classifiable as to Human Carcinogenicity" due to lack of [[statistical significance]] in previously examined rat tumor studies. In 1991, it was classified as Group E: "Evidence of Non-Carcinogenicity for Humans", and in 2015 and 2017, "Not Likely to be Carcinogenic to Humans".<ref>{{Cite web

One international scientific organization, the [[International Agency for Research on Cancer]] ([[International Agency for Research on Cancer|IARC]]), classified glyphosate in [[List of IARC Group 2A carcinogens|Group 2A]], "probably carcinogenic to humans" in 2015.<ref name=iarcmono/> The variation in classification between this agency and others has been attributed to "use of different data sets" and "methodological differences in the evaluation of the available evidence".<ref name=Tarazona/> In 2017, California environmental regulators listed glyphosate as “known to the state to cause cancer.” The state's Office of Environmental Health Hazard Assessment made the decision based in part on the report from the [[International Agency for Research on Cancer|IARC]]. State Proposition 65 requires the state office to add substances the international agency deems carcinogenic in humans or laboratory animals to a state list of cancer-causing items.<ref>{{Cite web |title=How chemicals are added to the Proposition 65 list |url=https://oehha.ca.gov/proposition-65/how-chemicals-are-added-proposition-65-list |access-date=2024-01-21 |website=oehha.ca.gov}}</ref>
