The study, published last week in the Journal of the National Cancer Institute, measured glyphosate levels in the urine of farmers and other study participants and determined that the presence of high levels of the pesticide was associated with signs of a reaction in the body called oxidative stress, a condition that causes damage to DNA.
Oxidative stress is considered by health experts as a key characteristic of carcinogens.
The authors of the paper — 10 scientists with the National Institutes of Health (NIH) and two from the Centers for Disease Control and Prevention (CDC) — concluded that their study “contributes to the weight of evidence supporting an association between glyphosate exposure and oxidative stress in humans.”
They also noted that “accumulating evidence supports the role of oxidative stress in the pathogenesis of hematologic cancers,” such as lymphoma, myeloma and leukemia.
“Oxidative stress is not something you want to have,” said Linda Birnbaum, a toxicologist and former director of the National Institute for Environmental Health Sciences. “This study increases our understanding that glyphosate has the potential to cause cancer.”
The study findings come after the CDC reported last year that more than 80% of urine samples drawn from children and adults contained glyphosate.
The CDC reported that out of 2,310 urine samples taken from a group of Americans intended to be representative of the U.S. population, 1,885 were laced with detectable traces of glyphosate.
