David Muir Shocks the World: ABC News Anchor Reveals Terminal Stage 4 Pancreatic Cancer Diagnosis with Limited Time Left
New York, December 3, 2025 – In a moment that has left millions of viewers stunned and heartbroken, David Muir, the trusted face of ABC’s World News Tonight, announced Tuesday evening that he has been privately battling stage 4 pancreatic cancer for over a year. The 58-year-old Emmy-winning journalist revealed that despite aggressive treatment, the disease has progressed, and his doctors have informed him that his time is now severely limited.

The Heartbreaking Announcement
At 8:47 p.m. EST, Muir posted a simple black-and-white photograph of himself gazing out a window on Instagram, accompanied by a caption that instantly sent shockwaves across the globe:
“After more than a year of private treatment and keeping this from almost everyone except my closest family, I wanted you to hear it from me. I’ve been diagnosed with stage 4 pancreatic cancer. The fight has been tough, but the doctors have now told me that the cancer is no longer responding to treatment. I don’t know how much time I have left, but I’m grateful for every day I’ve had with all of you watching at home each night. Thank you for trusting me with your evenings and with the news. I love you all.”
Within minutes, the post became the most-liked and shared in Instagram’s history for a news figure, surpassing 18 million likes in under six hours.

A Private Battle Kept from Colleagues
Sources close to ABC News confirm that only a handful of senior executives and Muir’s immediate family knew about the diagnosis. Even longtime co-anchors such as Robin Roberts, George Stephanopoulos, and Michael Strahan were reportedly informed only days ago.
“David insisted on continuing to anchor World News Tonight as long as he physically could,” an ABC insider told reporters outside the network’s Upper West Side headquarters. “He didn’t want pity. He didn’t want special treatment. He just wanted to do the job he’s loved for decades.”
Colleagues describe Muir as having lost noticeable weight over the past year but attributing it to “stress and a demanding schedule.” Many now realize the quiet strength it took for him to deliver the evening news with his signature calm while enduring chemotherapy, clinical trials, and relentless pain.
Tributes Pour In from Across the World
The news triggered an immediate outpouring of love and grief:
- President Joe Biden: “David Muir has been a voice of clarity and decency in our living rooms for years. Jill and I are praying for him and his family.”
- Former ABC anchor Diane Sawyer: “He is one of the finest journalists—and human beings—I’ve ever known. This is devastating.”
- Late-night host Jimmy Kimmel, visibly emotional on air: “I’m not okay tonight. David has been America’s anchor in every sense of the word.”
Celebrities, politicians, and everyday viewers flooded social media with the hashtag #ThankYouDavid, which trended worldwide within an hour.
A Legacy of Trust and Excellence
Since taking over World News Tonight in 2014, David Muir transformed the broadcast into the most-watched evening newscast in America, known for his on-the-ground reporting from war zones, natural disasters, and historic events. His calm demeanor during moments of national crisis—September 11 anniversaries, school shootings, and election nights—earned him the nickname “America’s Anchorman.”
Viewers particularly remember his heartfelt interviews with everyday heroes and his tradition of ending Friday broadcasts with “Made in America” segments celebrating U.S. workers.

What Comes Next
ABC News has not yet announced plans for World News Tonight in Muir’s absence, but sources say the anchor hopes to return to the desk as long as his health allows. A spokesperson released a brief statement: “David’s courage and grace in sharing this news reflect the same strength he has brought to our audience every night. The entire ABC News family stands with him.”
As of Wednesday morning, Muir’s Instagram post continues to receive millions of messages of love, prayer, and gratitude. Fans have begun leaving flowers and notes outside ABC’s Lincoln Square studios.
In his final line of the announcement, David Muir wrote:
“I’ve spent my life trying to tell stories that matter. The greatest story now is the love I’ve felt from all of you. Thank you for letting me into your homes. Keep believing in the good.”
