Thyroid lumps are commonly caused by the following reasons: first, endemic goiter, which is often caused by low iodine intake, need to go to the hospital to check the thyroid ultrasound and thyroid function for clarification. If this is the case, iodine supplementation treatment is needed. Second, nodular goiter, which is often caused by long-term over-excitement and high hormone secretion in the body, need to regulate lifestyle habits, such as reduce anger, do not eat too spicy food, do not drink alcohol, etc., and need to perform surgical treatment if necessary. Thirdly, thyroid tumors are both solitary and multiple. If the tumor is small, no malignant changes are considered, so don’t worry too much and have regular checkups. If there is any obvious change in the condition of the tumor, it may need to be treated with puncture therapy or interventional therapy, or surgical resection. There are also other diseases, such as malignant tumors of the thyroid gland. In conclusion, if a lump is found in the thyroid gland, regular checkups are needed and relevant treatment should be given according to the results.
