You can read and re-read all the journal articles about what percentages of Hurthle Cell Lesions are cancerous and what percentage are not. You can memorize all the factors that predict whether a HCL/N is cancerous or not. But NONE OF THAT can tell you whether your particular lump is malignant or not. Only surgery and a good pathologist can make that determination. YOU ARE JUST GOING TO HAVE TO WAIT TO FIND OUT. STARING AT SCHOLARLY WRITE-UPS ON YOUR COMPUTER SCREEN IS JUST GOING TO GIVE YOU A CRICK. SO GO TO BED ALREADY.
