Doctors say it's 'inconceivable' Biden's cancer went undetected by his medical team - as Trump Jr. questions if diagnosis is 'cover-up' | Several doctors have said it's "inconceivable" that former President [sic] Joe Biden's aggressive form of prostate cancer went undetected by his medical team -- as first son Don Trump Jr. even questioned whether the health diagnosis was part of a "cover-up." "It is inconceivable that this was not being followed before he left the Presidency," Dr. Howard Formman said in a post on X... Meanwhile, President Trump’s son Don Jr. went further in bluntly suggesting the news was hidden. "What I want to know is how did Dr. Jill Biden miss stage five metastatic cancer or is this yet another coverup???" the first son wrote on Truth Social.
