Frequently asked question: If a benign thyroid nodule turns out to be an adenoma, what does that mean?

A follicular adenoma is a nodule of thyroid hormone-producing cells. The diagnosis is made based on an ultrasound with a needle biopsy. You must also make regular visits to the hospital to check up on the development of the nodule.
If you have a toxic adenoma, you will produce extra thyroid hormone. This may result in the development of hyperthyroidism. A toxic adenoma does not disappear on its own; the nodule is usually removed surgically.
