The treatment for thyroid nodules depends on several factors. Small, asymptomatic nodules may only require regular monitoring with ultrasound exams. If the nodules are large or causing symptoms like difficulty swallowing or breathing, surgical removal may be considered. Radioactive iodine therapy can be used for some thyroid nodules that are overactive. In some cases, medications may be prescribed to manage thyroid hormone levels. Additionally, fine-needle aspiration biopsy may be done to determine if the nodule is benign or malignant. A comprehensive approach considering the individual's specific situation is crucial for the best treatment.
