82-year-old Biden diagnosed with prostate cancer: Last week, Biden sought medical attention due to worsening urination symptoms, and doctors found new nodules in his prostate. On Friday, he was diagnosed with prostate cancer, with a Gleason score of 9 (Grade 5), and it has metastasized to the bones. Although this represents a more aggressive type of cancer, the cancer still responds to hormone therapy, making it manageable through effective means. Biden and his family are currently evaluating treatment options with doctors.
