In the country, around 1% of all new cancer diagnoses yearly are that of the thyroid. This butterfly-shaped gland near the base of one’s neck regulates hormones, blood pressure, heart rate, weight, and body temperature. Any abnormal cell growth in this gland leads to cancer. While such a condition can strike at any age, those more vulnerable are between 25 and 65. Herein, we discuss the subtle warning signs of thyroid cancer and its causes. Silent warning signs of thyroid cancer Thyroid cancer does not exhibit any symptoms or indicators in its early stages. More often than not, it is found during a routine neck exam or during a scan used to identify other conditions. But if left untreated, it may form a lump that develops as a tumor. Below are some of the silent warning signs of thyroid cancer that should prompt one to seek medical help: Neck pain that begins at the front and seems to extend to the ears An unusual lump or nodule that one can feel through the skin of one’s neck A sudden change in one’s voice, including hoarseness Trouble breathing normally; one may feel like one’s breathing through a straw Inability to swallow with ease due to a nodule growing on the thyroid gland A feeling that tight-fitting shirt collars are becoming increasingly restrictive A persistent cough not caused due to cold Inexplicable throat pain Swollen lymph nodes Causes of thyroid cancer According to the American Cancer Society, the risk of thyroid cancer in women is three times higher than in men.
