Joe Biden has said the radiation treatment he received for his prostate cancer "worked as intended," in his first public comment on his own health since his son Hunter revealed the disease had spread to his bones. Writing on X to mark Prostate Cancer Awareness Month, the 83-year-old former US president thanked the medical staff who have cared for him and said he continues to focus on projects such as finishing his memoir. The update follows weeks of concern after Hunter Biden told the BBC that his father's cancer was "very painful" and "very debilitating," and that he wished Biden "would complain more" about it.

Biden's office first disclosed his diagnosis of an "aggressive" form of prostate cancer in May 2025, shortly after he left the White House, and he began radiation and hormone treatment that October following earlier skin cancer surgery. His wife, Jill Biden, said in June that because the cancer had spread to his bones, he would likely "live with cancer for the rest of his life." Former White House officials have also told reporters that Biden appeared increasingly fatigued during treatment, adding to long-running scrutiny of his health that intensified after his troubled 2024 debate performance. Biden plans to publish his memoir, "Promise Me, America," after November's midterm elections.
