Journalist Andrea Mitchell revealed that she's battling breast cancer on her MSNBC show Wednesday.

"I had planned to be hiking in Wyoming last week, but instead discovered that I am now among the 1 in 8 women in this country -- incredibly 1 in 8 -- who have had breast cancer," she said.

The 64-year-old said the disease "was discovered during my annual screening just a short time ago."

"Luckily for me, I am one of the fortunate ones; we discovered it in the earliest stage, it hadn't spread, and I'm already back at work with a terrific prognosis," Mitchell added.

Mitchell, who is also NBC's chief foreign affairs correspondent, then urged women to get annual screenings.

"I'm looking at this as another of life's lessons," she said. "For you women out there and the men who love you, screening matters. Do it. This disease can be completely curable if you find it at the right time."
