President Joe Biden has been diagnosed with prostate cancer, his office confirmed on Sunday. The 82-year-old received the diagnosis after seeking medical attention for urinary symptoms on Friday. According to his team, this marks the first time Biden has been formally diagnosed with prostate cancer.

The revelation has stirred fresh concern about Biden’s health during his presidency, especially given that the cancer has reportedly spread to his bones. Some medical professionals expressed surprise that the aggressive cancer went undetected for so long, though others noted that prostate cancers can sometimes progress rapidly without symptoms. Routine screening for prostate cancer is not typically recommended for men over 70, further complicating detection.

Former President Donald Trump weighed in on the diagnosis, suggesting a lack of transparency. Speaking at a White House event on Monday, Trump said, "I am surprised that the public wasn't notified a long time ago... it could take years to get to this level of danger." He implied that the diagnosis may have been concealed, a claim swiftly denied by a Biden aide.

The aide clarified that Biden had last undergone a Prostate Specific Antigen (PSA) test in 2014 and had never been diagnosed with prostate cancer before Friday. They added that he had been treated in the past for benign prostate enlargement but had not exhibited signs of cancer during his presidency.

Nonetheless, Biden’s condition has sparked debate amid ongoing revelations about how his health was managed during and after his time in office. Critics argue that voters were misled about the extent of his health issues during his 2024 re-election campaign. The controversy has been further fueled by the release of Original Sin, a new book by journalists Jake Tapper and Alex Thompson, which claims Biden showed signs of physical and cognitive decline in his final year in office. The authors report that Biden struggled to recognize people, including prominent figures like actor George Clooney, and had trouble recalling the names of key aides.

According to the book, Biden’s physical decline became so pronounced that aides considered placing him in a wheelchair—but only after the election. These revelations have prompted senior Democrats to acknowledge missteps. Senator Chris Murphy said Sunday, “It was a mistake for Democrats to not listen to the voters earlier.”

Vice President JD Vance expressed sympathy for Biden’s diagnosis but echoed calls for greater transparency. “We can pray for good health,” Vance said, “but if you're not healthy enough to do the job, you shouldn't be doing the job.”

Dr. Ezekiel Emanuel, an oncologist and former health adviser to Biden, stated that it is likely the cancer developed during Biden’s presidency. Speaking on MSNBC’s Morning Joe, Emanuel said, “He probably had it at the start of his presidency in 2021.”

Despite concerns, some doctors advise against jumping to conclusions. Dr. Robert Figlin of Cedars-Sinai Cancer emphasized that the aggressive nature of Biden’s cancer is not unprecedented. “Critics shouldn’t assume something was necessarily missed,” he told the BBC.

Prostate cancer is the second most common cancer in men, according to the Cleveland Clinic. The CDC reports that 13 out of every 100 American men will be diagnosed with prostate cancer in their lifetime, and 2 to 3 will die from it.

Biden’s case has reignited debate over medical transparency for public officials and the standards of care provided to aging leaders. While questions remain about the timing and detection of his illness, Biden’s office insists that there was no prior diagnosis or deliberate concealment.
