The most common symptoms of thyroid cancer include:
A lump or swelling over your thyroid or somewhere else in your neck
A cough that lasts, or won't go away, without symptoms of a cold
Hoarseness or other changes in your voice that are persistent
Neck or throat pain, especially in the front of your neck (near your Adam's apple) that can sometimes go up to your ears
Swollen lymph nodes
Swollen neck
Trouble breathing that feels like you are breathing through a straw
Trouble swallowing
Many of these symptoms may be caused by other health problems. But it is important to see your healthcare provider if you have these symptoms. Only a healthcare provider can tell if you have cancer.
