Former President Joe Biden did not release the results of a prostate-specific antigen blood test that could have caught his prostate cancer before it became aggressive.

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