In life, thyroid nodule is one of the very common diseases, it refers to the lump in the thyroid gland, which can move up and down with the thyroid gland with the swallowing action. Thyroid nodule can be divided into solitary and multiple nodules, and the possibility of cancerous transformation of solitary thyroid nodule is higher, so how to prevent the cancerous transformation of thyroid nodule? Let’s find out together. First of all, what are the causes of thyroid nodules? 1.Genetic factors: The chances of thyroid nodule disease are higher for those who have thyroid nodule in their family than for those who are ordinary people. 2.Consumption of food containing too much iodine Thyroid nodules are caused by too much iodine. Long-term consumption of a large number of iodine-containing seafood, iodine itself is not deficient, coupled with the usual diet is added to the iodized salt, which may cause iodine overdose. 3, testing technology The reason for the high incidence of thyroid nodules is also related to the testing technology. In the past, when doing thyroid examination, surgical palpation was mostly adopted. The location of the thyroid gland is relatively hidden, it is often difficult to find small thyroid nodules, but also with the experience of the detector, so the detection rate of nodules is also very low. 4, the increase in pressure With the increasing pressure of people’s lives, women are prone to significant endocrine changes. As a result, the chances of women suffering from thyroid nodules are very high. Why are thyroid nodules cancerous? Most of the thyroid nodules are benign, so patients do not need to worry too much. However, their treatment should not be neglected because they may become cancerous. The incidence of malignant nodules (cancer) is less than 1%, and the incidence of thyroid cancer in single nodules is also high. If it is malignant thyroid nodule, the mass can gradually increase in size, the patient up and down swallowing activities, there is a possibility of invasion of the trachea, appearing such as accompanied by hoarseness of voice, whooping, swallowing difficulties, or localized pressure and pain and other symptoms of compression. Patients who find thyroid lumps, first go to the hospital for ultrasound examination, the examination result is nodular (sexual) goiter, it is benign thyroid nodules; if the ultrasound suggests that the thyroid nodules are large and the border is not clear, with a little calcified foci, it is necessary to consider whether it is a malignant nodule, whether it is possible to have cancerous transformation. Thyroid cancer, the most common malignant tumor of thyroid, is a malignant tumor originated from thyroid epithelial cells, and most of the thyroid cancers are originated from follicular epithelial cells, which can be classified into papillary carcinoma and follicular adenocarcinoma according to pathological types. Among them, papillary carcinoma accounts for 60% of thyroid cancer. To prevent the harm of thyroid cancer, not only timely treatment, but also the patient’s own efforts are indispensable. Patients with thyroid disease should reasonably arrange their work, study and life, ensure enough rest and avoid exertion. In addition, you can exercise appropriately, so that you can enhance your physical fitness and immunity. They should also regulate themselves in terms of diet to prevent the cancer of thyroid nodules. What should I eat to prevent cancerous thyroid nodules? Eat more vegetables: such as green cauliflower, kale lei sprouts, kale, white cauliflower lei, mustard leaves, peaches and pears.
