Peter Jennings Has Lung Cancer

Peter Jennings has lung cancer

He's the last of the Big Three network anchors -- and Peter Jennings has some unsettling news of his own today. ABC says its longtime anchor has lung cancer and will begin outpatient treatment next week.

Jennings has anchored "World News Tonight" for more than 20 years. Dan Rather and Tom Brokaw joined him in the long-running trinity of anchors, until both stepped away from the desk in the past several months.
