The medical term for thyroid enlargement is "goiter." Goiter refers to a swelling of the thyroid gland, which is located in the front of the neck. It can vary in size and may cause a visible bulge or swelling in the neck.

It's important to consult with a healthcare professional to determine the cause and appropriate management of an enlarged thyroid gland.
