Katie Couric announces her breast cancer diagnosis

Katie Couric was diagnosed with breast cancer over the summer, and subsequently underwent surgery and radiation treatments that finished this week. 

As the former "CBS Evening News" and "Today" anchor explained in an essay published Wednesday by Katie Couric Media, where she shared her diagnosis for the first time, Couric learned of the cancer after a mammogram in June. She had missed a routine screening that should have taken place about eight months into the pandemic. 

"I was six months late this time. I shudder to think what might have happened if I had put it off longer," she wrote, encouraging people to attend their own screenings and schedule additional tests when warranted.
