Longtime friends and allies of Joe Biden say they are worried about the toll an aggressive form of prostate cancer is taking on the former president and his health. Biden, 83, announced last May that he was diagnosed with Stage 4 prostate cancer that had metastasized to the bone. Oncologists said some men with advanced prostate cancer can live many years with effective treatment while others deteriorate rapidly. “Bone metastasis is the most common place prostate cancer spreads but the degree is important and how it’s found,” Moul said. It is also common for metastatic prostate cancer to spread to the spine, said Gerald Denis, Shipley Prostate Cancer Research professor at Boston University Chobanian & Avedisian School of Medicine.
