There are many causes of calcification and treatment options need to be determined based on the specific cause. If the calcifications on the thyroid gland are small, they do not have any effect and do not require special treatment. In general, calcifications on the thyroid gland are not necessarily malignant, but some people may have calcifications on their thyroid nodules, which may require an ultrasound to check the grading of the thyroid nodules, also known as the TI-RADS grading of ultrasound. If the nodule is a grade 4 nodule, surgery is usually recommended; if the nodule is a grade 3 nodule or less, it can be observed and is less likely to be malignant. Calcified thyroid nodules with irregular edges and uneven internal echogenicity and a hard texture can be biopsied with fine needle aspiration to determine whether they are benign or malignant. If it is malignant, surgery should be performed as soon as possible and comprehensive treatment measures should be taken. If the thyroid calcification is large and there is pressure, hoarseness, difficulty in swallowing, or even a significant impact on breathing, it may cause breathing difficulties. In this case, surgery is required. If the thyroid function tests are normal, no special treatment is needed, but regular observation and review is required. Calcification of the thyroid gland should not be ignored to avoid delaying the best treatment.
