Former United States President Joe Biden is experiencing severe pain as his cancer continues to spread, according to a personal update disclosed by his son, Hunter Biden.

Hunter said the prostate cancer had metastasized beyond his father’s bones, suggesting that the disease may have progressed since the family first publicly acknowledged the diagnosis. He described its effects as both painful and debilitating, offering one of the clearest accounts yet of how the illness is affecting the former president’s daily life.

Biden’s office did not provide additional medical information on Saturday. A spokesperson declined to comment on Hunter’s statements, meaning there has been no new clinical report publicly detailing where the cancer has spread or whether his treatment plan has changed.

The former president revealed in May 2025 that doctors had diagnosed him with an aggressive form of prostate cancer that had already reached his bones. His representatives later confirmed that he was receiving radiation and hormone therapy—treatments commonly used to slow advanced prostate cancer and manage its symptoms.

Despite his health challenges, Biden has occasionally appeared at public events. He attended the dedication of former President Barack Obama’s presidential library in Chicago in June, but he has otherwise maintained a considerably quieter public schedule since leaving office.

The latest disclosure has prompted messages of concern from political figures and members of the public. It has also revived discussion about the immense physical strain faced by patients living with metastatic cancer, particularly when the disease affects the bones and other parts of the body.

Biden served as the 46th president of the United States from 2021 until 2025 and was the oldest person elected to the presidency at the time of his 2020 victory. His health was frequently debated during his time in office, although the cancer diagnosis was not announced until several months after his presidency ended.
