Hunter Biden said former President Joe Biden’s cancer is spreading, describing the disease as “very painful” and “very debilitating.”

Biden announced in May last year that has been diagnosed with prostate cancer’

“The cancer has spread, metastasized into his bones and further,” Hunter told the BBC’s “Newsnight” Friday. “It’s really sad to watch.”

Hunter became emotional during the interview while discussing his father’s condition, saying that it is “really hard” to watch his health decline.

“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,” he said. “He’s still doing his thing. He so believes in this country.”

Months after leaving the White House, Biden’s office revealed that the former president “was diagnosed with prostate cancer, characterized by a Gleason score of 9 (Grade Group 5) with metastasis to the bone.”

“While this represents a more aggressive form of the disease, the cancer appears to be hormone-sensitive which allows for effective management,” the statement continued. “The President and his family are reviewing treatment options with his physicians.”
