Thyroid cysts generally do not heal on their own and may not have obvious symptoms in the early stages, but it is also recommended to seek timely examination to clarify their nature to avoid subsequent adverse conditions. Thyroid cysts are generally classified as physiological or pathological. If the diameter of the cyst is less than 5 cm and there is no evidence of tumor lesion after examination, the cyst is considered physiological and should be closely followed up and examined once every 2-3 months, and the cyst may be found to be shrinking or not increasing when examined again. The cause of the lesion should be clarified and the possibility of malignant change should be excluded. In addition, there is no need to be nervous when thyroid cysts are found clinically, it is important to review them regularly, pay attention to a light diet, quit smoking, alcohol, coffee and other stimulating foods, and enhance the immunity of the body.
