Hi, pulitzer
My husband's FNA biopsy of his lymph node showed necrotic tissue, but not the cancer on the interior surface. The initial CT just showed the node. Fortunately, our HMO ENT was suspicious and escalated him to a Metrohealth doctor, who ordered a PET - that showed the tonsil tumor and the node. It is pretty scary that the initial test were negative (and a surface biopsy would have been, also). I am very thankful for the doctor's suspicions and skills!
