Former U.S. President Joe Biden‘s prostate cancer has spread beyond his bones and is causing significant pain, his son Hunter Biden said in an interview with BBC’s Newsnight. Reuters and the Associated Press reported the disclosure on August 8, bringing renewed attention to the former president’s health.

Hunter Biden said the cancer had metastasized to Biden’s bones and further into his body. He described the condition as painful and debilitating. Reuters reported that a spokesman for the 83-year-old former president declined to comment on Hunter Biden’s interview on Saturday.

Biden publicly disclosed his prostate cancer diagnosis in May 2025, less than four months after leaving the White House. At that time, his office said the disease had already spread to his bones. Reuters later reported in October 2025 that he was receiving radiation treatment and hormone therapy.

The latest comments from Hunter Biden provide a family account of how the illness is affecting the former president. They do not constitute a new medical bulletin from Biden’s doctors, and neither Reuters nor AP reported a new prognosis. That distinction matters because the new disclosure concerns the extent of the disease and the pain Biden is experiencing, rather than a formal change in treatment.

Despite his condition, Biden has continued to appear publicly. AP reported that Hunter Biden said his father remains engaged with issues he considers important. Reuters noted that Biden attended the dedication of Barack Obama‘s presidential library in Chicago in June, one of his recent public appearances.

Biden served as U.S. president from 2021 to 2025 after previously serving eight years as vice president under Barack Obama. His health and age drew sustained public attention during his presidency and during the 2024 election cycle. The current reports concern his cancer treatment after leaving office and should be separated from earlier political debate about his health.

As of August 8, the most recent confirmed information is that Hunter Biden says his father’s prostate cancer has spread beyond the bones and is causing substantial pain. Biden’s spokesman has not provided a separate medical update responding to those comments.
