Hurthle cell cancer doesn't always cause symptoms, and it's sometimes detected during a physical examination or an imaging test done for some other reason. When they do occur, signs and symptoms may include: 
A lump in the neck, just below the Adam's apple
Pain in the neck or throat
Hoarseness or other changes in your voice
Shortness of breath
Swallowing difficulty
 These signs and symptoms don't necessarily mean that you have Hurthle cell cancer. They may be indications of other medical conditions — such as inflammation of the thyroid gland or an enlargement of the thyroid (goiter).
