Constant Cough

Coughing is caused by throat irritation, and it has several well-known and generally innocuous causes, such as the common cold. It can also be a sign of thyroid cancer, especially if the patient does not have an upper respiratory illness and does not cease coughing.

Thyroid cancer can ultimately push against the trachea or windpipe, which is located just behind the thyroid. It can therefore irritate the trachea and its accompanying nerves, resulting in chronic coughing. A CT scan should be performed on a patient who has been diagnosed with thyroid cancer and has a chronic cough. The imaging examination can detect whether the tumor is to blame for the cough as well as the level of interaction with surrounding nerves.
