The illness Joe Biden disclosed more than a year ago has entered a more severe phase. His prostate cancer has spread to his bones and is causing pain, turning treatment from a defined medical episode into a permanent part of the former president’s life.
The seriousness of Biden’s condition was described by his son, Hunter, who said the disease had become painful and debilitating. At the same time, he stressed that his father continues to fight and has not withdrawn entirely from public life as long as his physical condition allows.
Biden’s aggressive prostate cancer diagnosis was announced in May 2025. By then, the disease had already metastasized to his bones — a stage at which treatment can slow progression, manage symptoms and extend life, but generally cannot eliminate the cancer entirely.
As Daycom noted in its earlier analysis, the deterioration in Biden’s health matters not only as a medical update about a former president. It also adds another dramatic turn to the biography of a politician whose final presidential campaign was already dominated by questions about age, stamina and physical capacity.
Biden did not disappear from public view after the diagnosis. He continued to appear at political events and recently delivered a speech at a Maryland Democratic Party fundraiser, almost exactly two years after the debate performance that effectively ended his attempt to seek another term.
That appearance carried particular symbolism. In June 2024, Biden’s weak and faltering debate against Donald Trump triggered a crisis inside the Democratic Party and eventually led him to abandon his re-election campaign.
Now, questions about Biden’s physical condition are no longer tied to electoral politics. They have become far more personal: he is living with metastatic cancer that requires continuous treatment and can increasingly affect mobility, endurance and the ability to withstand physical stress.
Prostate cancer is among the most common cancers in older men. In many cases, it grows slowly and can remain undetected for years. More aggressive forms behave differently, spreading beyond the original tumor and affecting other parts of the body.
Bone is one of the most common sites of metastasis. Once cancer reaches the bones, it can cause severe pain, weakness and other complications. In Biden’s case, this aspect of the disease is becoming increasingly central to his daily condition.
Jill Biden has also made clear that her husband’s treatment is ongoing. Her description was stark: he will continue living with cancer, and managing the disease has become a daily reality for the family.
Over the past year, the former president has undergone other cancer-related procedures as well. In 2025, skin cancer lesions were removed, and he later completed a course of radiation therapy. His family marked one stage of treatment with a video showing Biden ringing the ceremonial bell often used by cancer patients.
But prostate cancer remains the principal medical threat. Metastatic disease means doctors are no longer dealing with a localized tumor that can simply be removed, but with a systemic illness requiring long-term therapy and continuous monitoring.
For Biden, cancer also carries a deeply personal family history. His eldest son, Beau Biden, died in 2015 at the age of 46 from glioblastoma, an aggressive form of brain cancer. The loss became one of the defining tragedies of Biden’s life.
After Beau’s death, cancer research became one of Biden’s most personal policy causes. For years, he championed federal efforts to accelerate cancer diagnosis, treatment and the development of new therapies.
Now the politician who made the fight against cancer part of his presidential legacy is himself living with an incurable form of the disease. The symmetry is severe, but Biden has so far shown no intention of disappearing completely from public life.
His health has survived major crises before. In 1988, Biden underwent surgery for a brain aneurysm — a condition that posed an immediate threat to his life and could have ended his political career decades before he reached the presidency.
For much of his career, Biden’s ability to return after personal and physical setbacks became part of his public image. At 83, however, metastatic cancer creates a different reality. The challenge is no longer recovering from a single episode, but managing a disease that will remain with him.
His public appearances therefore carry a different meaning now. They are not preparation for another campaign or an attempted return to power. They are better understood as a sign that Biden still wants a place in Democratic politics and a voice in public debate.
He is also expected to publish a memoir, “Promise Me, America,” after the November midterm elections. The book could become one of his most significant attempts to define how the final chapter of his political career will be remembered.
That matters particularly because of the abrupt ending to his 2024 campaign. His withdrawal from the race left behind difficult questions about how long those closest to him understood the extent of his age-related limitations and whether the decision to step aside could have come sooner.
His current cancer diagnosis does not answer those political questions, and it should not be used to make retrospective medical assumptions about his presidency. But it inevitably changes the way his final years in office and public life are viewed — shifting the conversation from political fitness to serious illness.
Hunter Biden has described his father’s determination in the simplest terms: as long as he is alive, he will keep fighting. The phrase now carries a different weight. It is no longer campaign rhetoric, but the language of a family confronting a painful, progressive disease.
Joe Biden’s major political career is effectively over. But the final stage of his public life is still unfolding — between treatment, pain, occasional appearances and an effort to shape his own place in history. Increasingly, that final chapter is being defined not by Washington, but by illness.
