Former "Good Morning America" cohost Joan Lunden revealed on Tuesday that she has been diagnosed with breast cancer.
The 63-year-old journalist talked about her medical scare with current "GMA" host Robin Roberts, who is a breast cancer survivor.
Lunden's cancer didn't show up on a mammogram but was discovered during an ultrasound. She is beginning treatments shortly, including chemotherapy.
"I knew the minute the doctor came in the door," she recalled. "I could tell by her demeanor. 'You have breast cancer.' The words are so surreal." Lunden added that her cancer is aggressive. "You can't be afraid," she said. "That is what can really cause problems."
The TV veteran said she is optimistic about her prognosis, and urged women everywhere to get their annual checkups.
She also took to her blog to talk about her prognosis, writing, "I have decided to talk about my breast cancer because since the moment I took the job at Good Morning America I have lived my life sharing my joys and my disappointments with all of you: my pregnancies, my relationships, my career… I have shared my journey. So it certainly didn’t feel right keeping this part of my journey a secret."
Several high-profile journalists have had cancer scares lately. In addition to Roberts, who has battled breast cancer and myelodysplastic syndrome, "GMA" news anchor Amy Robach recently completed chemotherapy for breast cancer.
