In this preview clip from Sunday's brand-new episode of Keeping Up With the Kardashians, Kris confronts Khloe about refusing to get a DNA test like the rest of her sisters.
"I haven't been bugging you about this but I feel like you should really get on the bandwagon and try and get this DNA test done," Kris says. "The BRCA test will tell you if you have a genetic susceptibility to getting breast cancer."
"Mom, I don't want to is the point. I don't really care," Khloe fights back.
"It's unacceptable for you to have this technology at your fingertips and not go out and utilize that so that it might save your life one day," Kris responds.
"I don't care!" Khloe yells back. "I really don't care."
"You don't care if you get breast cancer?" Kris asks.
Khloe screams, "Fact: I'm going to die. You're going to die. We're all going to die!"
Things only get more heated from there! Watch the clip to see Kris and Khloe's dramatic fight for yourself.
