Overview

• Former President Joe Biden has been diagnosed with aggressive prostate cancer (Gleason score 9) that has metastasized to his bones, and he is consulting on treatment options.
• President Donald Trump falsely claimed Biden was at a nonexistent 'stage nine' of cancer and suggested the diagnosis had been withheld during Biden's presidency.
• Medical experts, including Dr. Eric Feigl-Ding, clarified that cancer staging ranges from 0 to 4 and is distinct from the Gleason score, which measures tumor aggressiveness.
• Trump's comments, which included boasting about his own cognitive test results, drew widespread ridicule and criticism for their inaccuracy and perceived insensitivity.
• Public discussion has shifted to correcting Trump's misinformation, highlighting the severity of Biden's diagnosis, and debating the politicization of health and fitness in leadership.
