Thyroid Nodules

Many people have thyroid nodules without knowing, which are harmless in most of the cases, but sometimes they might be serious.

Thyroid nodules

Thyroid nodules are lumps that manifest on the thyroid gland, and they can be solid or fluid-filled.

Thyroid nodules are very common, and most people don’t know they have them until discovering them by a routine medical exam.

Causes of thyroid nodules

• Overgrowth of thyroid tissue, which occurs for no clear reason, and they aren’t serious unless they become large and cause symptoms.
• Thyroid cysts, which are fluid-filled lumps.
• Multinodular goiter (an enlarged thyroid gland).
• Iodine deficiency.
• Thyroid cancer.

Symptoms of thyroid nodules

In most of the cases, thyroid nodules don’t cause symptoms unless they are large; then they:

• Can be felt.
• Can be seen, like a swelling at the base of the neck.
• Can cause pressure on the windpipe, which might lead to shortness of breath.
• Can cause pressure on the esophagus, which might lead to swallowing difficulties.
• Might cause hyperthyroidism.

Diagnosis of thyroid nodules

• Physical exam.
• Thyroid function tests.
• Ultrasound.
• Biopsy.

Treatment of thyroid nodules

Treating thyroid nodules depends on the type of the nodules:

• Keeping them under monitoring without any treatment.
• If the nodules aren’t cancerous but are large and cause annoying symptoms, they can be removed by surgery.
• If the nodules are cancerous, they are treated depending on the case.
