A thyroid nodule is a swelling that develops in the thyroid gland. It can be due to growth of thyroid cells or a collection of fluid known as a cyst. Thyroid nodules are relatively common. They can be felt in approximately 6% of women and 2% of men. Sensitive testing by ultrasound can reveal small nodules in as many as one third of all adults.

Thyroid nodules can cause problems for patients in three ways:
They can become large enough to press on nearby structures in the neck, such as the swallowing tube (esophagus) and windpipe (trachea).
Most thyroid nodules are benign growths that may increase in size but do not spread beyond the thyroid gland. About 5% of nodules turn out to be malignant growths, which are cancers that can spread beyond the thyroid gland to other parts of the neck and other areas of the body. One of the most important questions that should be answered when a thyroid nodule is identified is whether it may represent a form of thyroid cancer.

The thyroid is one of the larger endocrine glands - 10-20 grams in adults- and butterfly-shaped: the wings correspond to the lobes and the body to the isthmus of the thyroid.
The superior thyroid artery is the first branch of the external carotid, and supplies mostly the upper half of the thyroid gland, while the inferior thyroid artery is the major branch of the thyrocervical trunk, which comes off of the subclavian artery.
A nodule or lobe of the thyroid is sometimes removed for biopsy or for the presence of an autonomously functioning adenoma causing hyperthyroidism.
