I heard today an interesting fact: GWB, Obama, Trump, and Biden, when they had their physicals the lab reports of all the negative test were made public, however, only Biden's reports omitted PSA levels. Like I said, when you are having the level of exams that a president goes through, and how often they are having casual intermediate consults with the doctors, advanced, metastasized cancer does not just suddenly appear with no prior warning signs.
