Symptoms

Thyroid cancer can cause many symptoms, including:

• A lump or swelling in your neck. This is the most common symptom.
• Pain in your neck and sometimes in your ears.
• Difficulty swallowing.
• Difficulty breathing or constant wheezing.
• Hoarseness that is not related to a cold.
• A cough that continues and is not related to a cold.

Some people may not have any symptoms. Their doctors may find a lump or nodule in the neck during a routine physical exam.
