After his father died in 2013 from a cancer that started in his kidney, Michael Hickey was troubled by more than his grief. John Hickey was 70, never smoked and rarely drank. 
He did work a night shift at a Saint-Gobain textile plant in their hometown of Hoosick Falls, New York. The plant historically produced fabrics coated with a Teflon-like substance, similar to nonstick pans and other products. When a local schoolteacher also died from cancer shortly afterward, Hickey’s suspicions skyrocketed.
