CNN's Sara Sidner reveals false stage 4 cancer scare after PET scan, biopsy clears spread

CNN anchor Sara Sidner told viewers on August 7, 2026, that a PET scan falsely suggested her stage 3 breast cancer had spread to her liver, lungs, spine, and hip — pointing to stage 4. After 15 days, a tissue biopsy and a molecular blood test confirmed the cancer had not spread. Her doctor's lesson: "biopsy beats scan."
