Katie Couric wants to talk about body parts that most people would rather not discuss.

"We have to use `colon,' `rectum,' `bowels.' The more matter-of-fact you are with the language, the more it helps," she said in the October issue of Good Housekeeping.Couric's husband, NBC legal commentator Jay Monahan, died of colon cancer in January. The "Today" show host is anchoring a five-part series on the disease.

"Too many Americans don't get tested because they don't want to talk about that part of their body," she said. "You can't be squeamish about it. It might cost you your life."

The mother of two said her sorrow is still overwhelming at times. "You can forget about it temporarily," she said. "But then the grief comes like a huge wave and like a horrible invasion of your heart and soul."
