The incidence of thyroid nodules is now on the rise, so let’s talk about this today. First of all, the cause of the disease is unclear, but it is thought to be related to iodine deficiency and thyrotropic substances, so experts recommended iodine supplementation for the whole country. Why is this so? In fact, it is clear from domestic and international studies that iodine deficiency causes endemic goiter and that iodine supplementation is only useful for preventing endemic goiter. There are many other causes of the disease, some of which are already known, such as excessive iodine, atmospheric pollution, and environmental pollution, and some of which are not known at all! So, how to prevent it when the cause is not even clear? Secondly, let’s talk about what to do if you have a nodule. It is very simple, you only need to do the eight thyroid functions and ultrasound of the thyroid and cervical lymph nodes, and especially emphasize that CT is not usually needed; take the results to an experienced specialist. There are several common mistakes to avoid at this time, patients chasing after ultrasonographers for their opinion, asking for the opinion of acquaintances, and rushing to a major hospital. Please note that if a visit to the doctor can be solved by an ultrasound, why do you need a clinician? The specialist will decide, based on all the test results, whether you need further tests, whether to puncture, whether to use medication, whether to operate, and how often to recheck! Thirdly, to popularize a knowledge, there are four types of thyroid cancer pathology, the most common one is papillary cancer, which has an excellent prognosis and hardly affects your life. As for you have to worry about the rare type, that is the mentality! Fourth, where to do the surgery. You can do it wherever you want, trust is important! I can only tell you secretly, you can ask them a few questions, how big an incision is needed? Do clearing? Do intraoperative freezing? How does the incision meet? Fifth, medication for the thyroid is complex and must be reviewed to be clear. If you have a benign nodule that you suspect on ultrasound, if you don’t have compression symptoms, you can use medication and follow the doctor’s recommendations to review it on time! It can also be treated with radiofrequency. Surgery, one is open surgery, the choice and size of the incision has a great impact on the beauty! The second is lumpectomy, and from the neck small incision to do, and from the armpit to do, there are also from the areola to do, according to the doctor’s proficiency to decide. The first one below is done by other hospitals, the second one is the open surgery we do, and the third one makes our lumpectomy axillary approach.
