WASHINGTON — The revelation that former President Biden has advanced prostate cancer generated more questions than answers on Monday, prompting debate among experts in the oncology community over the likely progression of his disease and resurfacing concerns in Washington over his decision last year to run for reelection.
Biden’s private office said Sunday afternoon that he had been diagnosed earlier in the week with an “aggressive form” of the cancer that had already spread to his bones, after urinary symptoms led to the discovery of a nodule on his prostate.
But it was not made clear whether Biden, 82, had been testing his prostate-specific antigens, known as PSA levels, during his presidency — and if so whether those results had indicated an elevated risk of cancer while he was still in office or during his campaign for reelection.
