It is possible to get other cancers with thyroid cancer. The presence of occupancy in other areas needs to be determined by imaging and reference pathology results to determine whether it is metastatic thyroid cancer or other cancers newly developed. The thyroid gland itself is the largest endocrine organ in the body and is mainly responsible for metabolism. Thyroid cancer patients mostly occur in women and is related to hormones, such as with sex hormones. Breast cancer patients will have their thyroid gland reviewed regularly after surgery, and thyroid cancer patients will also have their breast gland reviewed regularly after surgery. Because endocrine is different from lymph nodes and sweat glands, which carry lymph fluid and sweat through ducts, but the thyroid gland makes hormones, which are then secreted into the bloodstream and then act on various organs, there is a possibility of problems elsewhere. Papillary thyroid cancer must be reviewed regularly by a doctor after surgery. Thyroid cancer also requires thyroxine tablets after surgery, and the dose should be adjusted according to the patient’s condition. Therefore, it is important to follow the doctor’s orders and have regular review to adjust the amount of thyroid hormones and also to review thyroglobulin to predict the recurrence of thyroid cancer.
