Other forms: goiters
A goiter is an unusually enlarged thyroid gland that results in a protusion on the neck.
If you've ever seen someone with a large growth on their neck, it may have been a goiter. Goiters are a result of the thyroid gland producing too much or too little hormone. Goiters can also develop because you're not getting enough iodine in your diet. A goiter can be small, but it can also become extremely large and unsightly. If you even think you're getting a goiter, it's a good idea to see a doctor.
