Thyroid cancer occurs in the cells of the thyroid. The thyroid is responsible for producing hormones that regulate heart rate, blood pressure, body temperature, and weight. Typically, in the early stages of thyroid cancer, there are no symptoms. However, as the cancer progresses one may have the following symptoms: a lump that can be felt through the skin on one’s neck, changes to one’s voice, difficulty swallowing, pain in neck and throat, or swollen lymph nodes in the neck. Thyroid cancer remains relatively rare in the United States, but is becoming more common as new technology enables doctors to find small thyroid cancers that may not have been detected previously. Treatment options are dependent on the individual’s type and stage of thyroid cancer.
