Is it normal to have small nodules in the thyroid gland?
I am a 45-year-old woman. During a recent physical examination, I was found to have a small nodule in my thyroid gland. My doctor said there's no need to worry for now, but I still feel confused. Is it normal to have a small nodule in the thyroid gland?

It is usually normal for small nodules to appear in the thyroid gland, especially in adults. Thyroid nodule formation may be related to aging, hormonal changes, insufficient iodine intake, or long-term stress. Most thyroid nodules are benign and do not pose a threat to health or require specific treatment. However, a small number of nodules may carry a risk of malignancy, so they should not be completely ignored. Ultrasound examination can provide a preliminary assessment of the nodule's characteristics; when necessary, fine-needle aspiration biopsy may also be used to confirm the diagnosis.
If thyroid nodules are detected, it is recommended to undergo regular follow-up examinations to monitor any changes. Generally, an ultrasound examination should be performed every 6 to 12 months to observe whether there are any abnormalities in the size, shape, or internal structure of the nodule. Maintain a healthy lifestyle, avoid excessive fatigue and mental stress, and consume iodine-containing foods, such as kelp and nori, in a balanced manner. However, do not blindly supplement iodine. If symptoms such as difficulty swallowing, hoarseness, or noticeable neck swelling occur, seek medical advice promptly.
