Exclusive: WHO cancer agency asked experts to withhold weedkiller documents
In a letter and an email seen by Reuters, officials from the International Agency for Research on Cancer (IARC) cautioned scientists who worked on a review in 2015 of the weedkiller glyphosate against releasing requested material. The review, published in March 2015, concluded glyphosate is "probably carcinogenic," putting IARC at odds with regulators around the world. Critics say they want the documents to find out more about how IARC reached its conclusion.
