Biden was diagnosed following urinary symptoms, one of the most common signs of prostate cancer. That's because it is often detected only when the prostate is big enough to have impacted the urethra, the tube that connects the bladder to the penis.

Former President Joe Biden's office says he has been diagnosed with prostate cancer. The finding came after the 82-year-old reported urinary symptoms, which led doctors to discover a nodule on his prostate.

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