NEW YORK (AP) — Former "Good Morning America" host Joan Lunden said she has breast cancer.
Lunden disclosed her diagnosis on Tuesday's edition of the ABC morning show, which she co-anchored from 1980 through 1997. She spoke with "GMA" host Robin Roberts, who has also been treated for breast cancer recently, as has "GMA" co-host Amy Robach.
Lunden said her treatment will include surgery and radiation, and said she's already started chemotherapy.
She also said after the initial shock of the diagnosis, she's resolved to learn everything she can about the illness and go into what she called "warrior mode."
Lunden, 63, is now a health and wellness advocate and has written eight books.
