A group of leading medical experts is expressing skepticism about the timing of the recent somber announcement concerning Joe Biden’s diagnosis of aggressive prostate cancer, which was reported on Sunday to have metastasized to his bones.

While acknowledging the seriousness of the situation and not detracting from the well-wishes extended to the former President and his family, a number of doctors have commented on social media about the news. They appear doubtful that this is actually recent information within Biden’s close circle.

Dr. Howie Forman, a professor specializing in radiology and biomedical imaging, public health management, and economics at Yale, finds it “inconceivable” that such an aggressive cancer was not being monitored prior to Biden leaving office.

Forman indicated that the cancer being at this advanced stage would have been monitored “for some time before this diagnosis.”

The concern becomes just how far back his doctors, friends, and family may have known about the cancer. Could it be possible that the cancer just sprang up aggressively out of nowhere for an elderly president who medical experts constantly monitor?

Cancer touches us all. Like so many of you, Jill and I have learned that we are strongest in the broken places. Thank you for lifting us up with love and support. pic.twitter.com/oSS1vGIiwU
