The term "nódulo SA" refers to a specific type of thyroid nodule that is often evaluated for its potential to be cancerous. Thyroid nodules are lumps that can form in the thyroid gland, which is located in the neck and produces hormones that regulate metabolism. Most nodules are benign, but some may require further investigation through imaging or biopsy to determine their nature. Diagnosis of a nódulo SA typically involves ultrasound examinations and, if necessary, fine-needle aspiration biopsy. The results help healthcare providers decide on the appropriate treatment, which may include monitoring, medication, or surgery. Early detection and evaluation are crucial for effective management of any potential thyroid issues.
