Thyroid cancer

Most thyroid cancers are highly treatable, and small papillary cancers may not need immediate surgery — active surveillance is a real option now.

What to know first

  • Papillary is the most common type and generally has excellent outcomes.
  • Small (<1 cm) low-risk papillary cancers may be safely watched, not immediately removed.
  • Molecular testing on biopsies can avoid unnecessary surgery for indeterminate nodules.

When to see a doctor

  • A new lump in the neck or a nodule felt on the thyroid
  • Persistent hoarseness or a change in the voice
  • Difficulty swallowing or a feeling of pressure in the neck
