Neuroendocrine tumor: Don't know for sure, but it looks like your doc is checking for a neuroendocrine tumor - one that secretes hormones that might be the cause of your diarrhea. He/she's also checking for a rare type of thyroid cancer, which is also hormonally active (you've had prior thyroid cancer) and can be seen in patients with other neuroendocrine tumors. Discuss with your doc for more exact explanation.

See below: Your studies are normal. This means you do not have excess cortisol- cushing's syndrome. You do do need excess cortisol to be bipolar.
