Thyroid nodules are solid or fluid-filled lumps that form in the thyroid, a small gland located at the base of your neck, just above your breastbone. Most thyroid nodules are harmless and cause no symptoms. Only a small percentage of thyroid nodules are cancerous.

Fine needle aspiration cytology, or FNA for short, applied in diagnosing thyroid nodules is considered the most effective method due to its accuracy of over 95%; with a positive predictive value of 89-98%, a negative predictive value of 94-99%; and false negative and false positive rates of less than 1%. FNA has helped select the right cases requiring surgery, reducing the number of cases requiring surgery by more than half, which means reducing treatment costs.

I have a thyroid hypoechoic tumor with irregular edges called Tirads 4 and have had several benign biopsies. Doctor, can you tell me if a benign thyroid hypoechoic tumor called Tirads 4 should be operated on? Thank you very much, doctors.

Many people, when diagnosed, are extremely worried and wonder “is thyroid nodule dangerous?” or "What medicine do thyroid tumors take?". However, in fact, malignant thyroid nodules can be considered as benign cancerous diseases.
