”Thyroid cancer is all around us” is a bit alarming, but there is still a basis for clinical findings. The thyroid gland is a butterfly-shaped organ located on both sides of the trachea in the neck. It is the largest endocrine gland in the body and is in charge of metabolism and the speed of other organs in the body. This engine often has some minor faults, if repaired in time, it will be “new”; if it is in disrepair, and the “minor faults” become “big trouble”, it It will be “scrapped”, and then the human body will be greatly affected. When there is a problem with the thyroid gland, it may appear as a thyroid nodule. According to the official statistics, the prevalence of thyroid nodules is as high as 18.6%, which means that nearly one out of every five people has a thyroid nodule, and about one third of the patients with thyroid nodules need surgery, Thyroid cancer has become an invisible killer, how can we detect the latent crisis in the neck at an early stage? It is clinically found that thyroid cancer is mostly asymptomatic in the early stage, which gives these latent cancer cells a chance to “muddle through” and makes it very difficult to detect these “enemy elements” in time. Nevertheless, we can still look for some “traces” to confirm their existence and then nip them in the bud. First, we can learn a set of self-examination methods: a look: in the mirror, stretch the neck, swallow saliva, see if there is a lump with the swallowing action up and down. Second touch: place your right thumb on the right side of the trachea under the laryngeal node, and touch the left side of the trachea with the rest of your fingers, and feel if there is a mass sliding under your fingers when you swallow. Similarly, switch to the left hand and then check the right side of the trachea. If you find a mass after self-examination, or if you have a history of previous neck radiation exposure or treatment, or if you have a family history of thyroid disease, or if you have a recent change in voice, dysphagia, or irritating cough, you need to go to a thyroid specialist at a large hospital for a detailed examination, including neck palpation, neck ultrasound, and thyroid function tests. If the nodules have abnormal blood flow, calcification, uneven texture, unclear border, irregular shape and enlarged lymph nodes, you should be alert to the occurrence of thyroid cancer; if necessary, a small sample of suspicious cells can be taken with a fine needle for laboratory test to determine whether cancer has occurred. If you find a thyroid nodule that has a tendency or possibility of cancer, you should undergo surgery at an early stage. Early stage thyroid cancer, if treated with timely and reasonable surgery, can have a long survival period and even “revert” to a normal person after surgery. However, if early stage cancer becomes late stage cancer, the result after surgery will be much worse and the survival period after surgery will be greatly reduced. In conclusion, thyroid cancer is a treatable malignant tumor, in fact, it is not scary, what is scary is that it is found late; the earlier it is found and the earlier it is treated, the better the result will be; therefore, we need to raise awareness, find it in time and deal with it correctly to solve the crisis of the neck rationally.
