Summary
Former President Joe Biden was diagnosed with an aggressive form of prostate cancer that has metastasized to the bone, a diagnosis considered unusual for someone who undergoes regular screenings. Most prostate cancer cases are detected early, but 8% present at advanced stages, indicating Biden may have had the disease for years. Screening recommendations vary, with the American Cancer Society advocating for screenings in men over 50, while the U.S. Preventive Services Task Force suggests discussions for those aged 55 to 69, leading to a decline in screenings and an increase in advanced diagnoses.
