I will scale back book promotion events because of cancer, says former president Biden

Former US president Joe Biden announced on Sunday that because of his cancer he will not be able to take part as much as expected in promotional events for his forthcoming memoir.

"Some days are better than others; the disease has not stopped me, but at times it slows me down," he wrote on social media. He added, however, that he believes the book's words will speak for him.

The book, titled Promise Me, America, is due to be released on November 17. It will cover his presidential years, the challenges he faced, the decisions he took and America's role in the world, he said.

Biden, who turns 84 on November 20, is currently the oldest living US president. Within four months of leaving the White House, in May 2025, he disclosed that he had cancer. Although it was a somewhat aggressive form, his office said at the time that it was hormone-sensitive, allowing effective treatment.
