Valerie Harper: Cancer Can't Kill Happiness

Valerie Harper was in a great mood over the weekend, looking great and laughing it up as she talked to Savannah Guthrie about her terminal illness.

Harper was on "Today" ... discussing her brain cancer prognosis and the prospect that she may only have 3 months to live.  A very wise Harper said, "If you die, you're not a failure.  You're just somebody who had cancer, and that's the outcome."

Harper also said she keeps her mind open to miracles.
