Thyroid Cancer Symptoms  

Thyroid cancer can be completely asymptomatic for months or years. In most cases, the cancer grows very slowly without causing any apparent symptoms. As the tumor increases in size, you may notice presence of a nodule (a small mass) in your lower neck. In general, thyroid cancer can cause the following symptoms:  

• lower front neck mass 
• hoarse voice  
• pain in the throat or neck  
• difficulty breathing  
• difficulty swallowing  
• diarrhea  
• Swollen lymph nodes in your neck.  

  If you experience these symptoms, it does not mean you have thyroid cancer; in fact, about 5% of mass in the neck are cancerous. Therefore, if you notice a lump in your neck, consult your doctor before assuming anything.
