ABC's "World News Tonight" anchor announced Tuesday night he has lung cancer.
Lung cancer is the number one cancer killer of both men and women. Local oncologists say it has a 15 percent survival rate, but they are hopeful those survival rates will improve in the next several years with new research.
Noah Smith, spokesman for the Great Lakes Division, American Cancer Society says while there is nothing good about a diagnosis of lung cancer, having someone like Peter Jennings with lung cancer heightens the public's awareness about how devastating the disease can be.
Smith says it sends a clear message to people not to smoke, or to get help and quit if they are already addicted.
Jennings says he had quit smoking 20 years ago, but started again after Sept. 11, 2001.
