Monsanto’s Roundup® is currently the largest-selling and most widely used herbicide in the world. It is used in both agricultural and residential settings as a weed killer. However, glyphosate, the active ingredient in Roundup, has been classified by the World Health Organization as a probable carcinogen. Therefore, millions of people who have used Roundup are at risk for developing cancers, including non-Hodgkin Lymphoma.
