Joe Biden’s Promise Me, America Tour Limited by Cancer Diagnosis

Former President Joe Biden said Sunday that his prostate cancer diagnosis has limited his energy and will force him to make fewer appearances promoting his forthcoming presidential memoir.

Biden, who disclosed his cancer diagnosis last year after leaving the White House, said on X that his doctors “continue to be encouraged” by his response to treatment. He also acknowledged that “some days are better than others.”

“While writing the book, I was diagnosed with cancer, a disease known all too well to millions of Americans and their families,” Biden, 83, wrote.

“Some days are better than others. It hasn’t stopped me, but sometimes it slows me down. Unfortunately, that means I won’t be able to have as many conversations about my book as I had hoped. Still, I’m hopeful the words on the page will speak for themselves.”

“Promise Me, America” is set to be published Nov. 17.

“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.

“What we stand for, America’s role in the world and, above all, my faith in the American people and the great American experiment in self-governance and democracy.”

Last month, the 46th president shared a personal update about his health during Prostate Cancer Awareness Month and urged men to visit their doctors for early detection.

“By the time we found it, it had already spread to my bones,” Biden wrote on social media. “When prostate cancer is caught early, the five-year survival rate is close to 100%.”

He also thanked his medical team, writing: “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.”

Biden completed treatment for stage four cancer in October 2025. His son, Hunter Biden, has described his father’s condition as “very debilitating.”

“The cancer has spread, metastasized into his bones and further,” Hunter said in August. “It’s very painful, and it’s very debilitating in many respects.”

Biden’s memoir follows the June release of a book by former first lady Jill Biden, “A View from the East Wing.”
