Some thyroid cancers can come back after removal, so monitoring for recurrence is important.

The thyroid gland is located in the lower front part of the neck above the breastbone and regulates metabolism through production of thyroid hormones (T₃ and T₄). Thyroid cancer is a malignant tumor of the thyroid gland. Papillary and follicular thyroid cancers are the most common types, and are known as differentiated thyroid cancers because they process iodine similarly to normal thyroid tissue. Surgery is the initial treatment for papillary or follicular thyroid cancers.

After initial treatment, long-term monitoring is needed to check for recurrence of the cancer. This is done by repeat ultrasound examinations of the neck, radioactive scanning, and measuring thyroglobulin levels in the blood.

小号OME甲状腺癌可以取出后回来，所以监测复发是很重要的。

甲状腺位于胸骨上方颈部下部的前部，通过甲状腺激素（T ₃和T ₄）的产生来调节新陈代谢。甲状腺癌是甲状腺的恶性肿瘤。乳头状和滤泡性甲状腺癌是最常见的类型，并被称为分化型甲状腺癌，因为它们与正常甲状腺组织相似地处理碘。手术是乳头状或滤泡性甲状腺癌的最初治疗方法。

初始治疗后，需要进行长期监测以检查癌症是否复发。这是通过对颈部进行反复超声检查，放射性扫描以及测量血液中甲状腺球蛋白水平来完成的。
