The announcement offers a rare personal glimpse into the former president’s life away from Washington, where his focus has shifted from the daily pressures of governing to confronting a serious medical challenge.
Biden Admits Cancer Is Slowing Him Down
In a message published Sunday on X, Biden explained that his cancer diagnosis came while he was working on the book documenting his time in the Oval Office.
Rather than abandon the project, he continued writing while undergoing treatment.
But the former president acknowledged that his condition has made it impossible to maintain the schedule of interviews and public discussions he had initially planned.
“While writing the book, I was diagnosed with cancer, a disease known all too well to millions of Americans and their families,” Biden wrote.
He then offered a candid assessment of how the illness has affected his everyday life.
“Some days are better than others. It hasn’t stopped me. But sometimes it slows me down. What that means is, unfortunately, I won’t be able to do as many conversations about my book as I’d hoped. However, I’m hopeful the words on the page speak for themselves.”
The admission marks a significant adjustment for a political figure who spent more than five decades in public office.
Biden has continued to defend his administration’s record since leaving Washington, but his latest statement suggests that his health will determine how frequently he can personally participate in those discussions.
Despite the limitations, Biden reported that his physicians “continue to be encouraged” by his progress.
That positive assessment, however, does not erase the seriousness of his diagnosis.
Cancer Had Already Reached Biden’s Bones When Doctors Discovered It
The former president’s medical difficulties became public in May 2025, when his office announced that doctors had identified an aggressive form of prostate cancer.
By the time the disease was discovered, it had already metastasized to his bones.
Cancer that has spread beyond its original location generally requires more extensive treatment and ongoing medical monitoring.
Although therapies can help control advanced prostate cancer, the disease can cause significant pain, fatigue, and physical limitations.
Biden underwent radiation treatment in October 2025, an important step in his broader cancer-care regimen.
He subsequently indicated that the treatment had achieved its intended purpose.
Nevertheless, his latest remarks demonstrate that encouraging medical results do not necessarily mean a patient has returned to normal health.
For Biden, even routine professional obligations now appear to require additional consideration.
Hunter Biden Previously Revealed How Painful His Father’s Condition Had Become
The former president’s latest announcement follows troubling comments from his son, Hunter Biden, who publicly discussed the severity of his father’s illness in August.
Hunter described the disease in particularly stark terms.
“The cancer has spread, metastasized into his bones and further,” Hunter said. “It’s very painful, and it’s very debilitating in many respects.”
Those remarks provided a more troubling picture of the physical challenges Biden was confronting behind the scenes.
While the former president has emphasized his determination to remain active, his son’s description highlighted the toll that metastatic cancer can take even when treatment is underway.
The family’s public comments have also brought renewed attention to the importance of detecting prostate cancer before it advances.
During Prostate Cancer Awareness Month in September, Biden encouraged men to discuss screening and early detection with their physicians.
“By the time we found it, it had already spread to my bones,” Biden wrote on social media.
He also expressed gratitude for the professionals overseeing his care.
“Their skill, dedication, and compassion mean so much. The radiation treatment from last fall worked as intended, and I continue to do the things I care about, like finishing my memoir,” he said.
His remarks suggest that completing the book has become an especially meaningful personal milestone during treatment.
Biden Prepares to Defend His White House Legacy in New Memoir
The forthcoming publication is expected to provide Biden’s own account of the decisions, controversies, and major events that shaped his presidency.
His four years in office included the chaotic American withdrawal from Afghanistan, persistent inflation concerns, contentious immigration policies, and escalating international conflicts.
Republicans repeatedly criticized his administration over border security, federal spending, and the direction of the American economy.
His presidency also ended under extraordinary political circumstances.
Following widespread concerns about his age and ability to serve another term, Biden withdrew from the 2024 presidential race, leaving Vice President Kamala Harris to lead the Democratic ticket against Donald Trump.
Trump ultimately returned to the White House, setting the stage for a renewed debate over Biden’s political legacy.
The former president’s memoir will give him an opportunity to present his version of those events without relying on former advisers or political commentators to interpret his decisions.
Biden described the book’s purpose in expansive terms.
“It covers my years as President. The challenges we faced, the decisions I made, and why I made them. It’s about who we are as a nation,” Biden said.
He continued:
“What we stand for. And America’s role in the world. More than anything, it’s about my faith in the American people and the great American experiment in self-governance and democracy.”
For conservative readers, the publication will likely raise familiar questions about the administration’s handling of major domestic and foreign-policy challenges.
It may also provide new insight into Biden’s decision to seek reelection before ultimately abandoning his campaign.
Whether the book directly addresses those controversies remains to be seen.
A Different Chapter for the Former First Family
Biden’s upcoming memoir follows the publication of former first lady Jill Biden’s book, “A View from the East Wing,” which arrived in June.
Together, the publications represent an effort by the former first couple to document their years in Washington and shape the historical understanding of Biden’s presidency.
But the former president’s latest health announcement adds a deeply personal dimension to that effort.
Instead of traveling extensively to promote his account, Biden now faces the prospect of allowing the written work to carry much of his message.
His announcement also underscores the contrast between the demands of political life and the realities of confronting a serious illness at 83.
Biden has not indicated that he intends to abandon public life altogether, and his physicians’ encouraging assessment offers a measure of hope.
Still, the decision to reduce appearances is a reminder that his battle with cancer remains an ongoing and consequential part of his post-presidential years.
For now, Biden appears determined to finish telling his story, even if his health prevents him from discussing it as often as he once hoped.
And while Americans remain sharply divided over his record in the White House, his latest disclosure brings attention to a struggle that extends far beyond partisan politics.
