What are the different treatments for thyroid nodules?

Most Are Benign: Doctors' dont "treat" thyroid nodules unless there is concern for cancer or they get big enough that they cause problems. Solitary nodules are more concerning for cancer than thyroids with multiple nodules in them. If there is a concern for ca they are biopsied. If worrisome, the half portion of the thyroid with the nodule is removed, not just the nodule. See my comment below for more.

Depends: Some nodules are observed, some are recommended to be removed via a hemithyroidectomy or total thyroidectomy. All nodules over 1 cm need to be evaluated by an endocrinologist or thyroid surgeon and many will need to be biopsied.
