Thyroid cancers can cause a variety of signs and symptoms.In many cases, the first symptom of early stage thyroid cancer may be a lump or nodule in the neck. These growths, which sometimes grow quickly, may be noticed by the patients themselves or by a physician during a routine examination. Other common signs and symptoms of thyroid cancer include:

• Neck pain, sometimes extending up to the ears
• Hoarseness
• Difficulty swallowing
• Breathing difficulty
• A cough that continues and is not caused by a cold

Patients are encouraged to contact their physician when they experience these symptoms. In many cases, these symptoms may be related to other conditions, such as benign thyroid nodules. Awareness of potential thyroid symptoms can help early diagnosis. Although it is rare, some thyroid cancers may not cause symptoms until after the disease has progressed to an advanced stage.
