The thyroid gland is the gland that makes and stores hormones that help regulate the heart rate, blood pressure, body temperature, and metabolism. Thyroid hormones are essential for the function of every cell in the body. They help regulate growth and the rate of chemical reactions in the body. Thyroid hormones also help children grow and develop. The thyroid gland is located in the lower part of the neck, below the Adam's apple, wrapped around the trachea. It has the shape of a butterfly with two lobes attached to one another by a middle part called the isthmus. The thyroid uses iodine, a mineral found in some foods and in iodized salt, to make its hormones. The two most important thyroid hormones are thyroxine (T4) and triiodothyronine…show more content…
Follicular tumors, on the other hand, grow only on one side of the gland. These tumors develop in the hormone-producing cells and account for 30% - 50% of all thyroid cancers (Thackery 1057). Medullary thyroid tumors account for 5% - 7% of all thyroid cancers, and are usually uncommon. Like papillary tumors, they grow on one or both sides of the gland. Anaplastic tumors, though extremely rare, develop on either side of the thyroid gland and spread rapidly to other parts of the body. It account for only 2% of all thyroid cancers but is the fastest growing, and most aggressive thyroid cancer type (Thackery 1057). The aggressiveness of each type of thyroid cancer is different. There are four main stages in each of the types of thyroid cancer except for anaplastic cancer (Rubin 91). In the stage I of papillary and follicular thyroid cancer, the cancer is located only in the thyroid and may be found in one or both of the lobes. In stage II if the patients are younger than 45 years of age, the cancer has spread beyond the thyroid. But if the patient is older than 45 years of age, the cancer is only in the thyroid and is larger than 1 centimeter. In stage III, the cancer is usually found in patients older than 45 years of age and has spread outside of the thyroid or has spread to the lymph nodes but not outside of the neck. In stage IV, the cancer is again usually found in patients over the age of 45. It most likely has spread to other parts of the
