Papillary Prognosis is Perfect
Anaplastic is Awful (not treatment responsive usually)
Medullary = MEN2, with most common presentation of hypercalcaemia therefore calcitonin-secreting
The presence of lymph node metastasis contrasts papillary thyroid cancer with follicular thyroid cancer, where haematological metastasis predominates.
