Former US President Joe Biden, 82, has been diagnosed with prostate cancer that has spread to his bones, a statement from his office said on Sunday.
Biden, who left office in January, was diagnosed on Friday after he saw a doctor last week for urinary symptoms.
The cancer is a more aggressive form of the disease, characterised by a Gleason score of 9 out of 10. This means his illness is classified as “high-grade” and the cancer cells could spread quickly, according to Cancer Research UK.
Biden and his family are said to be reviewing treatment options. His office added that the cancer was hormone-sensitive, meaning it could likely be managed.
In Sunday’s statement, Biden’s office said: “Last week, President Joe Biden was seen for a new finding of a prostate nodule after experiencing increasing urinary symptoms.
After news broke of his diagnosis, the former president received support from both sides of the aisle.
President Donald Trump wrote on his social media platform Truth Social that he and First Lady Melania Trump were “saddened to hear about Joe Biden’s recent medical diagnosis”.
Former Vice-President Kamala Harris, who served under Biden, wrote on X that she and her husband Doug Emhoff are keeping the Biden family in their prayers.
In a post on X, Barack Obama – who served as president from 2009 to 2017 with Joe Biden as his deputy – said that he and his wife Michelle were “thinking of the entire Biden family”.
In the UK, Prime Minister Keir Starmer said: “I am very sorry to hear President Biden has prostate cancer. All the very best to Joe, his wife Jill and their family, and wishing the president swift and successful treatment.”
The news comes nearly a year after the former president was forced to drop out of the 2024 US presidential election over concerns about his health and age. He is the oldest person to have held the office in US history.
Biden, then the Democratic nominee vying for re-election, faced mounting criticism of his poor performance in a June televised debate against Republican nominee and current president Donald Trump. He was replaced as the Democratic candidate by his vice-president, Kamala Harris.
Prostate cancer is the second most common cancer affecting men, behind skin cancer, according to the Cleveland Clinic. The US Centres for Disease Control and Prevention (CDC) says that 13 out of every 100 men will develop prostate cancer at some point in their lives.
Age is the most common risk factor, the CDC says.
Dr William Dahut, the Chief Scientific Officer at the American Cancer Society and a trained prostate cancer physician, said the cancer is more aggressive in nature, based on the publicly-available information on Biden’s diagnosis.
He noted, however, that most patients tend to respond well to initial treatment, “and people can live many years with the diagnosis”.
Dr Dahut said that someone with the former president’s diagnosis will likely be offered hormonal therapies to mitigate symptoms and to slow the growth of cancerous cells.
Biden had largely retreated from the public eye since leaving the White House and he has made few public appearances.
The former president delivered a keynote speech in April at a Chicago conference held by the Advocates, Counselors, and Representatives for the Disabled, a US-based advocacy group for people with disabilities.
Biden has faced questions about the status of his health in recent months.
In an appearance on The View programme that also took place in May, Biden denied claims that he had been experiencing cognitive decline in his final year at the White House. “There is nothing to sustain that,” he said.
For many years, the president had advocated for cancer research.
In 2022, he and Mrs Biden relaunched the “cancer moonshot” initiative with the goal of mobilising research efforts to prevent more than four million cancer deaths by the year 2047.
Biden himself lost his eldest son, Beau, to brain cancer in 2015.
