Introduction
Under normal circumstances, thyroid nodules classified as category III rarely resolve spontaneously and often persist for a long time. If the nodule is a mild one caused by inflammation, it may shrink somewhat as the inflammation subsides. No special treatment is required if the nodule is clearly benign and shows no changes. However, if the nodule increases in size or undergoes changes in characteristics, it cannot heal on its own. If there are any concerns, it is recommended to seek medical advice in advance.
Under normal circumstances, thyroid nodules classified as level 3 rarely heal spontaneously and most often persist long-term. If mild nodules are caused by inflammation, they may shrink somewhat as the inflammation subsides. If nodules are clearly benign and show no changes, no special treatment is required. However, if abnormal growth or changes in nodule characteristics occur, spontaneous healing is not possible. If there are concerns, it is recommended to seek medical advice early. Detailed explanation is as follows:
Level 3 thyroid nodules caused by inflammation, such as acute thyroiditis, may decrease in size or even disappear after the inflammation is controlled. However, this scenario is relatively rare and requires close monitoring of nodule changes during inflammation treatment, along with following medical advice for follow-up examinations.
If a level 3 thyroid nodule is confirmed to be benign and causes no obvious symptoms, it generally will not resolve on its own and requires regular monitoring of its size and morphology. If the nodule exhibits abnormal growth, becomes harder in texture, or shows signs of calcification, these are indications of non-self-limiting changes. Further diagnostic evaluation and appropriate interventions are then necessary.
Patients should follow medical advice to undergo regular ultrasound examinations and thyroid function tests. Fine-needle aspiration biopsy may be necessary when indicated, to ensure timely monitoring of the nodule's characteristics and changes.
