Symptoms are not apparent with early thyroid cancer. Changes to the thyroid are often only found during exams or tests for other conditions.

In later stages, lumps may appear in the neck. The lumps may or may not cause pain. In some people, the lumps may grow fast. The lumps may press on nearby tissue and cause:

  • Neck pain, which may shoot up to the jaw and ears
  • Neck tightness or swelling
  • Hoarseness or other changes to voice
  • Persistent cough
  • Shortness of breath
  • Difficulty swallowing
