Former U.S. President Joe Biden has opened up about how his prostate cancer is affecting his everyday life, admitting that “some days are better than others.” The 83-year-old shared the update on social media ahead of the November 17 release of his presidential memoir, Promise Me, America. He revealed that he was diagnosed while working on the book and said his doctors remain encouraged by his response to treatment. He also expressed gratitude for the prayers and support he has received from the public.

Biden acknowledged that although his illness has not stopped him, it sometimes slows him down. As a result, he won’t be able to participate in as many book conversations and promotional events as he originally planned. Nevertheless, he hopes readers will connect with the words in his memoir. He ended his message by recalling advice from his father: “Champ, when you get knocked down, get up.”

Biden announced his diagnosis in May 2025, revealing that he had an aggressive form of prostate cancer that had already spread to his bones. His office explained that the cancer was hormone-sensitive, allowing doctors to manage it with treatment. He underwent radiation therapy in October 2025. Earlier this year, his son Hunter also spoke publicly about his father’s condition, describing the difficulties of watching him deal with the illness and its effects.

The update is especially emotional for the Biden family, who have already experienced the devastating loss of Joe’s son Beau, who died from brain cancer in 2015 at just 46 years old. As Biden approaches his 84th birthday on November 20, his message reflects both the challenges he continues to face and his determination to keep moving forward. His family and supporters remain hopeful as he continues his treatment.
