Andrea Mitchell revealed on air Wednesday that she's battling breast cancer.
"Mine was discovered during my annual screening just a short time ago," the journalist, 64, announced on her show
, Andrea Mitchell Reports
"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."
NBC's chief foreign affairs correspondent said she's now among the one in eight women in this country who have breast cancer and urged her viewers to get screened.
"I’m looking at this as another of life's lessons," Mitchell 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."
