As reported by CBS News, a cancer survivor is now fighting a battle against the product she says made her sick, the weed killer Roundup.

The woman, along with more than 30 others, are suing or plan on suing Monsanto, the maker of Roundup.

Monsanto has moved to dismiss the lawsuit.

Roundup’s main active ingredient is glyphosate. The lawyers base their cancer claims on a 2015 report from the International Agency for Research on cancer - or IARC - a division of the World Health Organization. It found glyphosate to be "probably carcinogenic." The report says glyphosate caused cancer in lab tests on animals and found that the chemical damaged DNA in human cells.

But Dr. Donna Farmer, who has studied the chemical at Monsanto for more than 20 years, strongly disagrees with IARC's findings.

"I can tell you glyphosate is safe. The data that they look at, they cherry pick it and then they interpret the studies completely different than research who actually did it," Farmer said.

Farmer said glyphosate targets a certain enzyme in plants that's not found in humans or animals. She said comprehensive long-term studies by both Monsanto and independent researchers show the chemical does not cause cancer.

The EPA is currently reviewing glyphosate as part of its ongoing, regularly occurring review process.
