Good Morning America co-anchor Robin Roberts announced that she has breast cancer. In an on-show announcement, Roberts told viewers that she will go into surgery on Friday and continue treatment afterwards. Roberts found a lump in her breast during a self-examination she gave herself after reporting on Joel Siegel's battle with cancer. Thankfully, her disease is in an early stage and a full recovery is expected.

In a statement to viewers, Roberts promissed that her "doctor expects me to be flying plans and hanging on to submarines in the middle of the Atlantic and scaling the Mayan Pyramids in no time in the mornings to come."

The in-house announcement from GMA's Senior EP, Jim Murphy:

"Good morning everyone. This morning our dear colleague and friend, Robin, has a personal announcement to make on Good Morning America. It involves her health. She has been wanting to share this news with all of her friends and colleagues here for several days but wanted to make sure she knew everything she was facing and could also share it with the public at the same time. So at 7:30 Robin will be telling folks she has been diagnosed with an early stage breast cancer. Her prognosis is good. Her spirit, as always, is strong. Her composure and grace have been remarkable to experience since she received the news. Her treatment will begin this Friday. Please keep her in your thoughts and prayers."
