Trouble Breathing

Difficulty breathing, often known as dyspnea, is another possible indicator of thyroid cancer — and it can be extremely concerning. In many situations, breathing problems are caused by a tumor that has grown large enough to partially obstruct the airway.

Even more concerning, dyspnea might suggest that cancer has spread to the lungs. The aberrant cells grow there, impairing the patient's capacity to breathe. Lung cancer cells eventually produce a number of consequences, some of which are deadly. While thyroid cancer has a relatively good survival rate, this is not the case if the illness spreads to the lungs. Cells that move to the lungs are the most prevalent cause of mortality in thyroid cancer patients; over half of them die from this consequence.
