Katie Couric says she's been treated for breast cancer

Katie Couric announced Wednesday that she was diagnosed with breast cancer in June and has undergone surgery and radiation treatment. In a first-person essay posted to her website, the news media personality, 65, said she received the Stage 1 diagnosis after missing an annual mammogram.

“I felt sick and the room started to spin,” she wrote. “I was in the middle of an open office, so I walked to a corner and spoke quietly, my mouth unable to keep up with the questions swirling in my head.”
