April 27 (UPI) -- The U.S. Supreme Court heard arguments Monday over whether herbicide companies such as as Monsanto can be sued for causing health effects like cancer.

Roundup, the most popular herbicide on the market, is at the center of the case with research indicating exposure to the weed killer could cause cancer. Monsanto, owned by Bayer, denies the link between the glyphosate-based product and cancer.

There have been more than 100,000 lawsuits filed in the United States against Monsanto over the health effects related to the weed killer. Bayer says it has spent about $11 billion on settlements.

Bayer is looking to the Supreme Court to determine whether it can be sued for the alleged health effects.
