@organizingkaos, what great news to hear that cabergoline is shrinking your wife's thyroid tumor.

"Cabergoline is a dopamine agonist that has been used as the first-line treatment option for prolactin-secreting pituitary adenomas for several decades. It not only suppresses hormone production from these prolactinomas, but also causes tumour shrinkage. Recent studies revealed some novel mechanisms by which cabergoline suppresses tumour cell proliferation and induces cell death."

OrganizingKaos, have you asked your wife's doctor about the supplements and complementary therapies, such as the ones you mention. Integrative therapies are increasingly accepted in cancer care. But you want to make sure that the ones you choose are complementary or not counterproductive. Some supplements may counteract the effects of treatment. I always refer to the National Center for Complementary and Integrative Health (NCCIH) to verify the evidence for complementary therapies. They have a great reference library and website here:
