The Genesis of the "Stage 9" Claim
The controversy surrounding "Trump stage 9 cancer" comments began when former President Donald Trump reacted to the news of Joe Biden’s prostate cancer diagnosis. On a Monday, Trump chose to flex his own "clean bill of health," while simultaneously casting doubt on the timing and nature of Biden's diagnosis. This immediately raised eyebrows, especially when he told reporters, "to get to stage 9, that’s a long time," confusing the cancer stage with the Gleason score. He further questioned, "you have to say, why did it take so long?" adding later, "Trump said he was shocked that the public didn’t learn about the diagnosis sooner, mistakenly referring to it as being 'stage 9.'" This statement was repeated twice, despite the clear medical fact that "there is no such thing as 'stage 9' cancer." The maximum stage for most cancers is Stage 4. This misstatement quickly became a focal point of discussion, with many, including comedian Jon Stewart, reacting in stunned silence to the medical inaccuracy. Trump appeared to conflate the Gleason score—a measurement of how aggressive cancer cells appear to be—with the stage of Biden's cancer. Biden's Gleason score was indeed 9, indicating a more aggressive form of prostate cancer, but this is distinct from the cancer's stage.Biden's Actual Diagnosis: Prostate Cancer with Gleason Score 9
According to a statement released by the office of former U.S. President Joe Biden in May 2025, four months after his term ended, he was diagnosed with "stage 4 metastatic prostate cancer." This diagnosis was characterized by a Gleason score of 9 (grade group 5) with metastasis to the bone. While this represents a more aggressive form of the disease, it is crucial to understand that "stage 4" is the highest and most advanced stage in the universally accepted cancer staging system, not "stage 9." The presence of metastasis (spread to other parts of the body, in this case, bone) is what defines it as Stage 4.Donald Trump: A Brief Overview
