In a poignant interview with the BBC, former U.S. President Joe Biden's son, Hunter, revealed that his father's prostate cancer has advanced and is causing him considerable pain and debilitation, having metastasized to other parts of his body. At 83 years old, Biden, who served as the oldest U.S. president, faced criticism throughout his tenure for allegedly concealing the extent of his health issues, particularly following a disastrous debate with his successor, Donald Trump, which led to his withdrawal from re-election bid. The former president announced his cancer diagnosis in May 2021, less than four months after leaving the White House. Hunter expressed sadness watching his father struggle and hoped he would express more about his health challenges, given their serious nature. Despite this, Joe Biden remains active in public discourse, advocating for issues that matter to him. The former president is set to publish a memoir titled "Promise Me, America" post the mid-term elections.
