Goiter is an enlargement of the thyroid gland due to a variety of causes. The condition can cause difficulty swallowing or breathing.
Hyperthyroidism occurs when your thyroid gland produces too much of the hormone thyroxine — speeding up your metabolism and sometimes leading to serious complications.
For people diagnosed with the most common forms of thyroid cancer, the prognosis is usually excellent.
Most thyroid nodules — lumps in the thyroid gland — cause no problems. But nodules that affect swallowing, produce excess thyroid hormone or are malignant require treatment.
