The incidence of this disease, which is more common in women and less in men, is increasing year by year. Thyroid tumors are divided into benign and malignant, and malignant tumors mainly refer to thyroid cancer, including papillary, follicular, medullary and undifferentiated carcinomas. From the overall incidence of thyroid cancer in the past, the incidence of thyroid cancer is not too high and it is a rather rare malignant tumor. However, the incidence of thyroid cancer is now gradually increasing. In 2010, the incidence of thyroid cancer in the United States, thyroid cancer in women has ranked the fifth and has entered the TOP 10 common tumors. Clinical statistics show that the ratio of female to male thyroid cancer patients is generally 3:1, and it is especially common in young and middle-aged women. One of the most important factors for the increasing incidence of thyroid cancer in recent years is the continuous improvement of examination methods, including the increasing resolution of ultrasound, which can help us detect thyroid cancer without clinical symptoms. Of course, there are other factors such as environment, diet (e.g. iodine content), radiation and hormonal environment which are also important factors in the rise of thyroid cancer incidence. How to prevent the occurrence of this disease? Staying away from radiation radiation does have a great impact on thyroid cancer. It is most common and most easily spread through the atmosphere by the radioactive substance iodine 131, which is needed by the thyroid gland to produce thyroid hormones. If iodine 131 is absorbed through the atmosphere or food and enters the body, it will easily form a collection in the thyroid gland, causing local internal irradiation and leading to malignant changes of thyroid follicular cells. Scientific iodine supplementation is prone to disease with too much or not enough iodine. Iodine is the main raw material for the synthesis of thyroxine by the thyroid gland, and with increasing practical experience, it has been recognized that iodine overdose or iodine deficiency can cause thyroid-related diseases. Therefore, it is important to supplement iodine scientifically and individually, not across the board. Pay attention to physical and mental health to keep your mood happy and take part in healthy exercises regularly, because the thyroid gland is an endocrine organ. Eat more vegetables and fruits, and pay attention to seafood, which is high in iodine. Only about 10% of thyroid nodules are thyroid cancer. In China, ultrasound plus cytological examination of thyroid gland with fine needle aspiration is recommended to determine whether thyroid nodules are malignant. If thyroid cancer is diagnosed, treatment is mainly surgical, and surgery takes a more central position in the overall treatment of thyroid cancer. In addition to surgery, the combination with isotope therapy, endocrine therapy and molecular targeted drug therapy is now advocated. This disease can be cured, the key is to be treated by specialists Generally, the treatment effect of common differentiated thyroid cancer is better, the statistics are ten years survival, twenty years survival rate, if the treatment is better, the ten years survival rate is above 90%, many patients can be cured for life. Of course, the prerequisite is early detection, early diagnosis and early treatment to truly cure. In China, the level of thyroid cancer treatment is still very high in thyroid specialties, especially surgical skills, and thyroid specialties are also able to implement treatment norms and comprehensive treatment well.
