Introduction
Benign thyroid nodules larger than 3 cm may be considered for surgical excision. If a thyroid nodule is excessively large and causes compression of surrounding organs, comprehensive evaluation—including thyroid function tests and thyroid CT—is strongly recommended. Symptoms such as dyspnea or dysphagia may indicate tracheal or esophageal compression by the nodule; in such cases, surgical excision is strongly advised.
In general, thyroid nodules larger than 3 cm typically require treatment. A detailed analysis follows:
For benign thyroid nodules exceeding 3 cm in size, surgical excision may be considered. If a thyroid nodule is particularly large and causes compression of adjacent organs, comprehensive evaluation—including thyroid function tests and thyroid CT—is strongly recommended. Symptoms such as dyspnea or dysphagia may indicate tracheal or esophageal compression by the nodule; in such cases, surgical resection is strongly advised. For nodules measuring ≤3 cm that are presumed benign, regular follow-up with thyroid ultrasound is recommended—typically every 3–6 months. If the nodule increases in size by ≥0.2 cm compared with prior imaging, fine-needle aspiration (FNA) biopsy should be considered.
Consuming foods with mild anti-inflammatory and swelling-reducing properties may also help alleviate symptoms and support treatment. Examples include Chinese cabbage, mustard greens, and kiwifruit. Patients should avoid spicy foods and refrain from using pungent seasonings—such as green peppers, chili peppers, scallions, or curry—during cooking, as these may exacerbate throat irritation and discomfort.
