3. Never biopsy a hot nodule => histology masquarades as follicular thyroid CA => unnecessary surgery.
4. Cold nodules in Grave's disease may still be malignant - investigate.
5. Cold nodules in MNG have malignant potential - investigate.
6. All palpable nodules should be viewed with US.
7. 5% of children receiving neck radiation go on to develop papillary thyroid CA, colloid adenomas.
