Washington: Exposure to Chemical in Roundup Increases Risk for Cancer

Exposure to glyphosate — an herbicide that remains the world’s most popular weed killer — increases the risk of some cancers by more than 40 percent, according to new research from the University of Washington School of Public Health.

The research team conducted an updated meta-analysis, a comprehensive review of existing literature, and focused on the most highly exposed groups in each study. They found that the link between glyphosate and Non-Hodgkin Lymphoma is stronger than previously reported.

“Our analysis focused on providing the best possible answer to the question of whether or not glyphosate is carcinogenic,” said senior author Dr. Lianne Sheppard, a professor in the Department of Environmental & Occupational Health Sciences and the Department of Biostatistics. “As a result of this research, I am even more convinced that it is.”

Their findings were published in the online journal Mutation Research/Reviews in Mutation Research. Co-author Ms. Rachel Shaffer is a doctoral student in the environmental and occupational health sciences at Washington.
