Are thyroid nodules common?

Yes, thyroid nodules are very common. Studies indicate that, by the time people reach their 60s, up to 50% of individuals may have thyroid nodules; many of these nodules go undetected as they are tiny and benign (non-cancerous). January is Thyroid Awareness Month, so let’s dig into this subject.

What Are Thyroid Nodules?

Found inside the thyroid gland, in front of the neck, thyroid nodules are lumps or growths. Their sizes, textures, and counts will differ as well. Although most nodules are benign—that is, non-cancerous—a tiny proportion may call for further testing for cancer.

How Are Thyroid Nodules Identified?

During a regular visit, a doctor may feel the neck region and find an enlargement or lump in the thyroid gland. Many thyroid nodules are discovered inadvertently during ultrasounds, CT scans, or MRIs conducted for unrelated conditions. For a carotid artery assessment, for instance, a neck ultrasound may show thyroid nodules. Those with a family history of thyroid disorders or those who have been exposed to radiation may have routine thyroid tests that result in early nodule discovery.

Thyroid nodule symptoms

  • a noticeable physical lump in the neck.
  • problems breathing or swallowing.
  • Hoarseness
  • Depending on whether the nodule is generating extra hormones (hyperthyroidism) or compromising thyroid function (hypothyroidism), different symptoms become noticeable.

After discovery, what happens?

Should a thyroid nodule be discovered, your doctor will probably advise more testing. This can include a thyroid ultrasound for evaluation of size, form, and features. Blood tests can help measure hormone levels, and finally a fine-needle aspiration biopsy will help one determine if the nodule is malignant. 

Doctor visits and knowledge of symptoms can assist in guaranteeing early identification and treatment. See your endocrinologist for the suitable assessment if you believe you have a thyroid nodule.
