Thyroid cancer is an abnormal growth of the cells of the thyroid gland, a butterfly-shaped gland located in the front of your neck just below the voice box (larynx). Thyroid gland secretes hormones that help regulate the body’s metabolism and levels of calcium. Thyroid cancer is more common in women than men. People who are exposed to high levels of radiation to the neck and have a family history of thyroid cancer and goitre (enlargement of thyroid gland) are at a higher risk of developing thyroid cancer.
Generally, surgery involving thyroid gland removal is the most common treatment of thyroid cancer. Total thyroidectomy is a surgical procedure to remove all of the thyroid gland. Subtotal or partial thyroidectomy is a surgery to remove part of the thyroid gland. Your doctor may also remove the lymph nodes if the cancer has spread to the lymph nodes. The surgery is performed under general anaesthesia. The surgeon removes the thyroid gland by making a 3-inch to 4-inch incision in the middle of your neck, on top of the thyroid gland. A small tube (catheter) will be placed into the area to drain the accumulated blood and fluids.
Thyroidectomy carries a risk of bleeding and infection, damage to your parathyroid glands resulting in low calcium levels in your blood. There is also a risk of damage to the nerves connected to your vocal cords and larynx, which can cause, hoarseness, coughing, swallowing problems, or speaking problems.
