Can Hyperthyroidism Be a Thyroid Cancer Symptom?

Hyperthyroidism is not considered to be one of the primary symptoms of thyroid cancer, although some studies suggest that up to 20 percent of people with thyroid cancer might also have hyperthyroidism. Hyperthyroidism occurs when the thyroid gland overproduces a hormone called thyroxine. This can lead to fatigue, unexpected weight loss, heart palpitations, mood swings, sleep disturbances and other similar complications.

What are the symptoms of thyroid cancer?

The most common symptoms of thyroid cancer are:

  • A chronic cough
  • Difficulty breathing
  • Difficulty swallowing
  • Neck pain
  • Voice changes
  • A palpable lump in the neck

Sometimes, a neck lump can be a result of hyperthyroidism rather than thyroid cancer. The thyroid gland itself can become swollen, which is known as a goiter. Or, a benign (noncancerous) lump can develop on the thyroid gland. A biopsy (tissue test) can be performed to determine if a thyroid nodule is cancerous.

Have your thyroid cancer symptoms evaluated by an experienced oncologist

If you’re experiencing unusual symptoms that you think might be related to thyroid cancer, it’s best to have them evaluated by an experienced oncologist. Thyroid cancer usually has a good prognosis, in part because many cases are detected before they have the chance to spread. Early detection can also lead to prompt treatment and a higher quality of life.
