A common weed-killer called “Roundup” contains the chemical glyphosate. Many users of this weed-killer have come forward stating that glyphosate has caused non-Hodgkin's lymphoma. However, Dr. Donna Farmer, a chemist at Monsanto, has stated that the glyphosate chemical targets a certain enzyme in plants that is not found in humans,
and as a result, her research shows that the chemical does not cause cancer. In addition to this, the Environmental Protection Agency (EPA) has found that glyphosate poses no cancer risk to humans. Additional research is is being conducted by the International Agency for Research on Cancer. Click here for more information about the research.
