What Are Thyroid Nodules?
2. Causes
There are numerous potential causes of thyroid nodules. One is a condition known as Hashimoto’s disease, which causes inflammation of the thyroid. Another is overgrowth of the thyroid tissue, which does not cause problems. Another is a goitre, which is the term for an enlarged thyroid gland, which is often caused by an iodine deficiency.
Some thyroid nodules are cysts, which are sacs filled with fluids, and these are usually non-cancerous. In a small number of cases, the nodules can be caused by cancer of the thyroid gland. Regardless of the suspected cause, it is advised to get the condition checked out as soon as possible.
