Former President Joe Biden’s prostate cancer has spread to other parts of his body and is causing him significant pain, his son Hunter Biden revealed during a Friday interview.

“The cancer has spread, metastasized into his bones and further,” Hunter Biden told the BBC in an interview which aired Friday. “It’s very painful and it’s very debilitating in many respects,” he added.

“It’s really sad to watch,” Hunter Biden said. “The only thing that I’d say about my dad, about his health right now, is I wish he would complain more, because it’s not good.”

Despite his poor health, Hunter Biden said his father is “still doing his thing,” and attending speaking engagements.

Joe Biden revealed his prostate cancer diagnosis in May 2025, just months after he departed the Oval Office.

The diagnosis at the time was that the cancer was Stage 4, “aggressive” and had already spread to his bones.

He received a Gleason score of 9, indicating both the cancer’s aggressive nature and the potential that he had been living with it for years.

“He had it while he was president,” said Dr. Ezekiel J. Emanuel, vice provost and oncologist at the University of Pennsylvania, adding Joe Biden “probably had it at the start of his presidency in 2021.”

“He did not develop it in the last 100 to 200 days,” Emanuel said, according to the American Journal of Medical Care.

Joe Biden’s wife, Jill, previously told the hosts of ABC’s “The View” that his cancer has slowed him down.

“He keeps his schedule, but he’s slowed down,” she said in June. “I mean, stage four cancer is — and he’s 83 — so, I think the mix of everything and the medications that he’s taken has made life a little more difficult these days.”
