Thyroid nodules are a more common condition in women. Through ultrasound, thyroid nodules can be found in 20-40% of the female population. Generally, thyroid nodules are operated on in the following cases: 1) when a malignant nodule is suspected, 2) when a single nodule is larger than 3 cm, and 3) when the nodule is large and affects your beauty. In your case, you can start with a fine needle aspiration of the nodule and decide whether to operate based on the results of the aspiration.
