Two Days of Monsanto’s RoundUp Use Per Year Doubles Cancer Risk

Unless you’ve been living in a cave somewhere, you’ve probably heard about the possible link between pesticides and cancer. Glyphosate-based pesticides, in particular, have been getting a lot of media attention as two ground-breaking lawsuits dealt a serious blow to Monsanto’s already unscrupulous reputation.

While Monsanto, now owned by the German corporation, Bayer AG, continues to declare its flagship pesticide—RoundUp—safe for use, a growing body of research and expert testimony says otherwise.

Dr. Dennis Weisenburger, a pathologist who testified in the recent lawsuit against Monsanto declared in the trial: “It’s not a hard call” to which he added, according to Courthouse News Service, that using RoundUp for more than 2 days per year doubles the risk of developing non-Hodgkin’s lymphoma.

Dr. Weisenburger was in private practice in Sacramento when he began noticing a sudden increase in non-Hodgkin’s lymphoma. He had already begun mapping Nebraska to determine whether there was a correlation between the disease and large concentrations of crops. As he stated in Courthouse News Service, “I tried to see if there was a correlation between intense agriculture and hematological malignancies, and there was a correlation.”

Weisenburger’s findings are supported by another recent study, which further strengthens the scientific link between the toxic chemical and cancer. The study, published in the medical journal Mutation Research/Reviews in Mutation Research, found an increased link between glyphosate-based pesticides and non-Hodgkin’s lymphoma (NHL). The study assessed whether exposures to glyphosate-based herbicides, like Monsanto’s RoundUp, increase the risk of non-Hodgkin’s lymphoma.

The meta-analysis assessed a variety of other scientific research before concluding that there is a “compelling link between exposures to glyphosate-based herbicides and increased risk for non-Hodgkin’s lymphoma.” Additionally, the researchers found potential links between glyphosate exposure and weakened immunity, hormone disruption, damage to genetic material that are all associated with non-Hodgkin’s lymphoma.

Additionally, this study confirms earlier findings in the International Journal of Environmental Research and Public Health which found a link between some pesticides and a significantly increased risk of non-Hodgkin’s lymphoma—a type of cancer of the lymphatic system. In this type of cancer, tumors of the lymph nodes or within the lymph system can form. After assessing 44 studies of 80 different pesticide ingredients, the scientists concluded that glyphosate exposure doubles the risk of cancer.

Since the losses of $78 million and $80.2 million in two jury-decided court cases against Monsanto, many new lawsuits have been filed against the company, bringing the total against the company to over 11,000 lawsuits. The rapidly-increasing registered lawsuits seem to spell financial disaster for Bayer AG.

That’s because Bayer paid $63 billion to purchase Monsanto and took over the company’s lawsuits. Since the recent court decision, Bayer’s stocks have dropped 40 percent in value, leaving the company’s total value at an estimated $39 billion. It’s unclear how far the company’s stocks will drop, but it is clear that the human and environmental destruction will be far worse.

Renata B the question remains are they actually protecting things by selecting one herbicide that is actually quite safe? Why are they not going after actually dangerous herbicides like Lasso which has not been allowed in some countries for many years because it was dangerous for the people applying it. Probably 20 + years ago it was taken off the market here and finally some other countries are removing it. It is still true that many activists are just against a company or 1 chemical because ????? they are just against them irregardless of what science says about them. That is why they still drink alcohol which is a KNOWN carcinogen. That is why they show a picture of a man spraying the crop vines with ??? and then talk about glyphosate or more likely Roundup when it they actually understood what they were writing about they would know that glyphosate would kill the crop the picture shows. But the picture makes the story look dangerous to all even when dirt is not true. So make rational choices about what you are going to do to 'save the planet' and base it on science not just a belief.

Bill Arthur, those antennae on your head, tell me, were there from birth? You are poisoning the earth. Feel proud of it. And yes, there is an agenda among activists: it is protecting and saving our (only) planet.
