The agrochemical giant Monsanto has desperately tried to hide research that links Roundup, the world’s most popular pesticide with cancer. Now documents revealed through lawsuits show how a respected EPA scientist’s conclusions that Roundup caused cancer were suppressed by the government agency meant to protect our health.
The U.S. Right to Know website has revealed a series of bombshell court documents raising serious questions about the weed killer’s safety and the research practices of its producer.
Senior Toxicologist Marion Copley worked in the EPA’s Health Effects Division for 30 years. She wrote a letter to an EPA director suggesting glyphosate, the active ingredient in Roundup, should be classified as a “probable carcinogen.” She listed more than a dozen health-damaging effects of glyphosate.
She listed 14 different mechanisms in glyphosate, which was originally created as a chelating agent, that could cause cancer: Chelators inhibit apoptosis, the process by which our bodies kill tumor cells, Chelators are endocrine disruptors, involved in tumorigenesis, Glyphosate induces lymphocyte proliferation, Glyphosate induces free radical formation, Chelators inhibit free radical scavenging enzymes requiring Zn, Mn or Cu for activity (i.e. SODs), Chelators bind zinc, necessary for immune system function, Glyphosate is genotoxic, a key cancer mechanism, Chelators inhibit DNA repair enzymes requiring metal cofactors.
Chelators bind Ca, Zn, Mg, etc to make foods deficient for these essential nutrients, Chelators bind calcium necessary for calcineurin-mediated immune response, Chelators often damage the kidneys or pancreas, as glyphosate does, a mechanism to tumor formation, Kidney/pancreas damage can lead to clinical chemistry changes to favor tumor growth, Glyphosate kills bacteria in the gut and the gastrointestinal system is 80% of the immune system, Chelators suppress the immune system making the body susceptible to tumors.
She noted that while any one of the above mechanisms could, in fact, cause tumors, glyphosate causes all those mechanisms simultaneously. Her conclusion – “It is essentially certain that glyphosate causes cancer.”
“For once in your life, listen to me and don’t play your political conniving games with the science to favor the registrants. For once do the right thing and don’t make decisions based on how it affects your bonus,” Copley said.
Marion Copley signed off her letter with: “I have cancer, and I don’t want these serious issues in MED to go unaddressed before I go to my grave. I have done my duty.”
