CHICAGO (WLS) -- Jurors in the first Sterigenics trial heard from the woman who is suing the Willowbrook company Thursday.
Susan Kamuda claims the emissions from the plant caused her breast cancer and her son's non-Hodgkin's lymphoma.
Kamuda said she does not have any history of cancer in her family and didn't know Sterigenics was releasing the chemical.
Sterigenics attorneys said there's no evidence to support Kamuda's claims.
The company is facing hundreds of lawsuits.
