PITTSBURGH (KDKA) — Former Pittsburgh Steelers player Merril Hoge is suing Monsanto, the company which makes the controversial weed killer, Round-Up.

According to the lawsuit, Hoge says Round-Up caused the non-Hodgkin’s lymphoma he developed in 2003.

After many rounds of chemotherapy, Hoge’s cancer went into remission.

Hoge says he was exposed to Round-Up for many years, starting back in 1977, when he worked on a farm.

Hundreds of similar lawsuits have been filed against Monsanto claiming the chemicals in Round-Up cause cancer.

Monsanto insists Round-Up is safe.
