This volume of research recently prompted the World Health Organization (WHO)’s International Agency for Research on Cancer (IARC) to call glyphosate out as a “probable human carcinogen.” This means the organization finds the chemical likely to be dangerous and to cause cancer.
What Research Says About a Link Between Glyphosate and Cancer
For decades, safety organizations have wavered on their stances on how safe glyphosate really is. The substance first found use as a pesticide in the United States in the 1970s. By the 1980s, the Environmental Protection Agency (EPA) warned that glyphosate could be dangerous.
However, this warning was short-lived. In the early 1990s, the EPA had changed its mind, citing a “lack of convincing evidence” that the chemical caused cancer. Workers in the agriculture industry continue to use glyphosate as an herbicide.
Since then, a number of studies conducted across the globe have suggested that the EPA’s original fear was correct. A Canadian study published in 2001 first showed that the number of glyphosate exposures a person has determines how much their cancer risk increases.
