The specific cause of thyroid nodule formation is not yet completely clear, and it is considered to be related to genetic factors, radiation factors, and abnormal amount of iodine intake.
1. Genetic factors: some patients with thyroid nodules have obvious genetic predisposition, especially malignant thyroid nodules.
2. Radiation factor: The thyroid gland is sensitive to radiation, and exposure to radiation may cause thyroid cell lesions, especially in people who received a lot of radiation to the thyroid gland when they were young.
3. Abnormal amount of iodine intake: Too little iodine intake may cause thyroid nodules, and the incidence of malignant thyroid nodules is significantly higher in iodine-deficient areas.
Patients who find thyroid nodules should go to the hospital for consultation and standardized treatment under the guidance of doctors.
