According to a study published in the Journal of the National Cancer Institute, herbicide exposure can result in oxidative stress, a condition that causes DNA damage. Scientists analyzed urine samples from people exposed to the substance and noticed biomarkers linked to the development of cancer and other diseases.

Evidence suggests that there is a role for oxidative stress in the pathogenesis of hematological cancers such as lymphoma, myeloma and leukemia, and increases understanding that glyphosate (the world’s most applied herbicide) has the potential to cause cancer.
People are exposed to glyphosate by using products made with the chemical and also by eating contaminated food and drinking water. In the study, scientists found glyphosate residues in a variety of popular foods and in waterways.
The authors focused on analyzing farmers exposed to glyphosate when they sprayed it in the fields, but they noticed similar results in non-farmers, which means that these effects may apply more widely to the general population, mainly through these other forms of contamination. .
Does glyphosate cause cancer or not?
As stated earlier, the study classifies the substance as potentially carcinogenic. The government-funded research comes at a time when US and European regulators are focused on assessing glyphosate’s safety and pushing for limits on the chemical’s use or requirements that products be labeled with a carcinogen warning.
But for now, regulatory agencies in many countries still say there is a lack of evidence linking glyphosate-based herbicides to cancer, and that it is one of the safest and most effective herbicides available. With this, it remains to wait for more research in the area, which brings evidence about this relationship.
