(CNN) Glyphosate, an herbicide that remains the world's most ubiquitous weed killer, raises the cancer risk of those exposed to it by 41%, a new analysis says. Researchers from the University of Washington evaluated existing studies into the chemical -- found in weed killers including Monsanto's popular Roundup -- and concluded that it significantly increases the risk of non-Hodgkin lymphoma (NHL), a cancer of the immune system. Bayer, which acquired Monsanto in 2018, said the same year that glyphosate is a "safe and efficient weed control tool." In 2015, however, the World Health Organization's International Agency for Research on Cancer classified glyphosate as "probably carcinogenic to humans." Moreover, the chemical has triggered multiple lawsuits from people who believe that exposure to the herbicide caused their non-Hodgkin's lymphoma.
