Internal echoes within a benign lesion may?

• A. Become more uniform
• B. Become more irregular
• C. Become more speckled
• D. Disappear

Answer: (A)

Internal echoes reflect the tissue makeup inside a lesion. Benign breast lesions tend to have a uniform, homogeneous echotexture because their internal tissue components are similar throughout. As a result, the internal echoes may become more uniform over time, which aligns with benignity. In contrast, malignant lesions often show irregular, heterogeneous or speckled internal echoes due to mixed tissue elements such as fibrosis, necrosis, calcifications, or varying vascularity, which disrupt uniformity. So a shift toward greater uniformity fits with a benign pattern, while increases in irregularity or speckling would raise suspicion for malignancy. Disappearance of internal echoes is not a typical benign feature.
