AP: ABC's Robin Roberts Has Breast Cancer

"ABC "Good Morning America" anchor Robin Roberts discovered she had breast cancer after following her own advice about early detection in a story about former colleague Joel Siegel's cancer death. Roberts, who announced her diagnosis on Tuesday's show, will undergo surgery on Friday.

"Hearing the words and saying it and seeing - it's surreal," Roberts, 46, told viewers in an on-air conversation with co-anchor Diane Sawyer.

Siegel, the ABC morning show's longtime film critic, died of colon cancer last month. During an ABC tribute to him, Roberts did a story about how early detection is key to surviving cancer. She went home that night and examined her breasts."
