Biden Says Cancer Would Have Stopped 2024 Run

In a People interview ahead of his memoir’s release, Joe Biden said he would not have pursued reelection in 2024 if he had known cancer was causing him to feel unwell, adding that an 80-year-old with cancer should not run for president. Biden said he was unaware of the illness while in office; he was diagnosed with metastatic prostate cancer after leaving the White House in 2025. He continued to defend his decision to run, saying he believed his experience made him the best person for the job, and argued that his June 2024 debate with Donald Trump was not decisive in his eventual withdrawal from the race. Biden ended his campaign in July and endorsed Kamala Harris, who later lost the general election to Trump.
