Thyroid cancer starts in the thyroid gland and can be defined as the growth of thyroid cells into abnormal cells. The thyroid glands are a small system of glands in the lower neck that produce hormones to manage the body's metabolism.
Thyroid cancer usually does not initially show symptoms but can be diagnosed when a lump is noticed in the neck. However, some patients may also experience symptoms such as difficulty swallowing, hoarseness, sore throat or shortness of breath.
The lethality of thyroid cancer can vary depending on the type and stage. When detected early, the chances of cure are high and many patients make a full recovery.
