Hypoechoic nodules are not always malignant and need to be judged in detail according to the specific situation. Hypoechoic nodules may be found during ultrasound examination. If the boundary between the nodule and normal tissue is blurred, and the patient also has systemic symptoms such as low-grade fever and fatigue, then it may be a malignant nodule. However, some hypoechoic nodules may have peripheral tissue, and the border with the surrounding normal tissue is relatively clear, then the chances of benign nodules will be greater. Whether the hyperechoic nodule is malignant or not, it is recommended to carry out pathological biopsy to further clarify the nature of the tissue, if the nodule continues to grow, it is best to consult a doctor for surgical excision in a timely manner, so as not to delay the condition and lead to serious consequences.
