Introduction

Hypoechogenicity on breast ultrasound refers to a nodule exhibiting lower echogenicity than normal breast tissue during the examination. This finding often suggests that the nodule may be of cystic-solid nature and could indicate underlying benign breast conditions such as fibrocystic changes or breast masses. Upon detection of hypoechogenicity on breast ultrasound, patients are advised to promptly undergo further relevant examinations to establish a definitive diagnosis and receive standardized treatment as directed by a physician, in order to avoid disease progression and potential adverse outcomes.

Low echogenicity in breast ultrasound refers to a finding where the nodule's echo is lower than that of normal breast tissue during a breast B-mode ultrasound examination. This often suggests the nodule may be a cystic-solid lesion and could indicate benign breast conditions such as fibrocystic changes or breast masses. Upon detection of low echogenicity on breast ultrasound, patients are advised to promptly undergo further evaluations to confirm the diagnosis and follow medical guidance for standardized treatment, so as to avoid delays that might lead to adverse outcomes.

Low echogenicity in breast ultrasound is an ultrasonic description used in imaging reports, characterizing how sound waves reflect within tissues. The ultrasound device emits high-frequency sound waves that travel through tissues and produce echoes; these reflections help determine the nature of the lesion. Low echogenicity alone does not indicate whether a lesion is benign or malignant. The assessment requires additional evaluation of features such as the size of the nodule, smoothness of its margins, presence of blood flow within the lesion, and calcifications, all of which contribute to a preliminary judgment about the lesion’s nature.

If the lesion is diagnosed as a benign fibroadenoma, it generally poses no serious concern and represents a common condition among women. Treatment typically involves surgical removal, followed by dietary attention and lifestyle adjustments to prevent recurrence. However, if the lesion is malignant—such as in cases of breast cancer—a comprehensive treatment approach including surgery, chemotherapy, and possibly radiation or targeted therapy—is required.

Which department should I visit for a breast ultrasound?

Breast ultrasound examinations can be scheduled through either the Breast Surgery Department or the General Surgery Department. For optimal results, breast color Doppler ultrasound should ideally be performed 7–10 days after the onset of menstruation. It is advisable to avoid scheduling this examination just before menstruation, as breast tissue often exhibits pronounced hyperplasia, local congestion, and edema during this phase—conditions that may obscure findings on color Doppler imaging. If abnormalities are detected on breast color Doppler ultrasound, a specialist from the Breast Surgery Department should evaluate and manage the condition.
