Former President Biden's prostate cancer has advanced to involve skeletal tissue, a development revealed through his son Hunter's interview with BBC Newsnight. The disclosure represents an important update regarding the president's health status beyond his previously announced diagnosis.

Hunter Biden characterised his father's medical condition as both acutely painful and substantially limiting in daily life. He expressed concern that his father was not adequately conveying the severity of his physical difficulties, suggesting the true extent of his struggles may not be fully apparent to the public.
