Glyphosate and cancer—revisited

merlin b e ba b d bb f articleLarge

I’ve already written about this topic back in 2015. Much of the information below is from that original blog post, but updated to include information published in the last few years.

Among this group of 54,251 pesticide applicators, there was no relationship between glyphosate exposure and non-Hodgkin lymphoma. This result is similar to previous analyses of the AHS data, which also showed no association between glyphosate and non-Hodgkin lymphoma.

And this study — even though it is only one study — makes it difficult for me to believe that any single case of non-Hodgkin lymphoma could be blamed on glyphosate. The largest data set we have (by far) which does the best job (by far) of accounting for confounding variables shows absolutely no association between handling glyphosate and developing non-Hodgkin lymphoma. A few years ago when I wrote about this topic, I noted that my mind could certainly change as new evidence came to light. At that time, the AHS study had relatively few cases of non-Hodgkin lymphoma – but in this most recent analysis, there were well over 500 cases to be analyzed. And again, there appeared to be no relationship to glyphosate.

So again, I’m not sure what the jury saw in this most recent case. But based on the evidence I have seen, I remain thoroughly unconvinced that glyphosate causes cancer.
