Former President Biden announced Friday that he's begun treatment for metastatic prostate cancer, reporting a positive prognosis. He described the treatment as a daily pill and expressed optimism, citing a surgeon's similar successful battle 32 years prior. Biden made his first public appearance since disclosing his illness at a veteran's event in Delaware, marking the 10th anniversary of his son Beau's death.
