What Exactly is a Thyroid Nodule?
A thyroid nodule is simply an abnormal growth of cells within the thyroid gland, located at the base of your neck. These lumps can be solid or fluid-filled and vary greatly in size. Some people have a single nodule, while others may develop multiple nodules over time.
Causes and Risk Factors
The exact cause of most thyroid nodules is unknown. However, certain factors can increase your risk, including being female, over 60 years old, or having a history of radiation exposure to the head and neck. Iodine deficiency, though rare in developed countries, can also play a role.
Symptoms: Silent or Noticeable?
Many thyroid nodules cause no symptoms and are discovered during routine check-ups. However, larger nodules may be visible or cause a feeling of fullness in the neck. In rare cases, nodules can affect thyroid hormone production, leading to symptoms of an overactive or underactive thyroid.
