The International Agency for Research on Cancer (IARC) monograph on the herbicide glyphosate became available on the agency’s website in late July. A working group convened by IARC to evaluate the carcinogenicity of glyphosate classified the herbicide as probably carcinogenic to humans. The working group found “limited evidence” in humans for the carcinogenicity of glyphosate, but cited a positive association for non-Hodgkin lymphoma. According to the monograph, there is “sufficient evidence” that glyphosate causes cancer in experimental animals. The monograph describes glyphosate as a “broad-spectrum, post-emergent, non-selective, systemic herbicide, which effectively kills or suppresses all plant types,” and a plant-growth regulator and desiccant when applied at lower rates. According to IARC, glyphosate has agricultural and non-agricultural uses throughout the world, including forestry, urban, and home applications. As of March 2015, glyphosate had the highest global production volume of all herbicides, the agency said in a press release. The monograph on glyphosate is available as a PDF on IARC’s website. Other IARC monographs are also available online. IARC Monographs identify and evaluate environmental factors that can increase carcinogenic risks to humans. IARC is the specialized cancer agency of the World Health Organization, and government agencies worldwide use its monographs as scientific support for their actions to prevent exposure to potential carcinogens.
