Former US President Joe Biden has been diagnosed with an aggressive, stage 4 prostate cancer that has spread to his bones. The diagnosis followed a recent doctor's visit for urinary symptoms. His Gleason score is 9, indicating a high-grade, rapidly growing cancer. While treatment options including hormone therapy and chemotherapy exist, they are not curative. Biden and his family are evaluating treatment plans, which may include clinical trials.
