Glyphosate and Cancer: A Textbook Case of “Manufacturing Doubt”
July 02, 2025 | Source: Sustainable Pulse
A recent study confirming the herbicide’s carcinogenic potential has been the subject of fierce criticism. However, this criticism is based on flawed scientific grounds, Le Monde has reported.
The recent publication of a study indicating an increased risk of various tumors in laboratory rats exposed to glyphosate has sparked numerous comments on social media and in the press, aimed at downplaying or denigrating this research.
These results, published on June 10 in the journal Environmental Health, only confirm the conclusions of the International Agency for Research on Cancer (IARC), which estimated in 2015 that the studies available at the time provided “sufficient evidence” of glyphosate’s carcinogenicity in animals.
The attacks on this study, led by the Ramazzini Institute in Bologna, Italy, offer an exemplary array of the sleight of hand of “doubt manufacturing,” a rhetoric aimed at undermining confidence in scientific results, often used to delay or fight regulatory decisions.
