During a recent press event on May 19, former President Donald Trump reacted to Joe Biden’s prostate cancer diagnosis, calling it “very sad.” However, he mistakenly referred to it as “stage 9,” a classification that doesn’t exist.

Biden was actually diagnosed with stage 4 prostate cancer, which is the most advanced stage, along with a Gleason score of 9—a measure of how aggressive the cancer is.

Trump expressed surprise that Biden’s condition wasn’t made public earlier, claiming, “To get to stage 9, it’s a long time.” Experts later clarified that cancer stages only go up to 4 and the number 9 Trump mentioned likely refers to the Gleason score.

After sharing his sympathy, Trump shifted focus to Biden’s cognitive state, questioning why mental health concerns hadn’t been addressed during his presidency.

“I think somebody is going to have to speak to his doctor,” Trump said, suggesting there may have been information the public wasn’t told. He also hinted that the former administration may have hidden the seriousness of Biden’s condition.

Donald Trump Jr. added fuel to the fire by calling out Jill Biden on social media, asking how she missed such an advanced case of cancer—again using an incorrect stage number. He echoed claims of a cover-up, sparking even more discussion online.

The incident has raised fresh questions and debates about transparency, health, and leadership, especially as the 2024 election race intensifies.
