A new Roundup trial is scheduled to get underway next week, as three cancer patients face off against Monsanto in the company’s former hometown of St. Louis, Missouri, alleging exposure to the company’s weedkilling chemical caused their illnesses.

July selection in the case is set to start August 1 in St. Louis County Circuit Court in Clayton, the seat of St. Louis County government. The three plaintiffs were chosen for the trial from the dozens of plaintiffs represented in a case titled Alesi v Monsanto.

Jurors will hear about the health problems of plaintiff Cheryl Davis, 70, who has suffered through two bouts with follicular lymphoma her doctors have told her is considered incurable, as well as the case of 65-year-old Marty Cox, who is in remission from diffuse large B cell lymphoma. Both of their lymphomas are types of non-Hodgkin lymphoma. Cox has a host of other medical issues including diabetes and has been a smoker.
