Donald Trump apparently believes Joe Biden has “Stage 9” cancer. There is no such thing as “Stage 9” cancer, but Trump repeated that twice Monday while talking to reporters about the former president’s revelation that he has aggressive prostate cancer that has spread to his bones.

“Last week, President Joe Biden was seen for a new finding of a prostate nodule after experiencing increasing urinary symptoms. On Friday, he was diagnosed with prostate cancer, characterized by a Gleason score of 9 (Grade Group 5) with metastasis to the bone,” the statement from Biden’s office said.

The former president released his first statement on X Monday morning, alongside a picture of him and his wife, Jill Biden, a day after the announcement: “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.”
