Research Article: Detection of Thyroid Nodule Prevalence and Associated Risk Factors in Southwest China: A Study of , Individuals Undergoing Physical Examinations
Abstract:
The thyroid gland, consisting of two connected lobes, is one of the largest endocrine glands in the human body, weighing – g in adults. Thyroid lesions are often found on the gland, with a prevalence of –%. Most of them are asymptomatic, and thyroid hormone secretion is normal. Thyroid nodules (TNs) are lesions that can arise as a consequence of localized abnormal thyroid cell proliferation. TNs are among the most common types of thyroid lesions, and TN incidence rates have risen to very high levels over the past three decades. A study has indicated that a TN prevalence rate of % in US. The most recent large-scale study conducted in estimated a TN prevalence rate of .% in China. While the majority of these TNs are benign, an estimated –% are malignant. While TNs do not cause notable clinical symptoms in most patients, their development is often related to various pathological thyroid conditions including autoimmune diseases, dysregulated endocrine function, and thyroiditis., Patients exhibiting symptomatic TNs generally undergo surgical resection, although this procedure can cause postoperative complications including hypothyroidism, infection, and damage to the laryngeal nerve. The effective treatment of TNs thus centers around the diagnosis and management of these nodules as early as possible in their development.
