Which statement best describes the typical features of a fibroadenoma on breast examination?

• A. Fixed, irregular, and tender
• B. Soft, fluctuant, tender
• C. Diffuse, non-fixed, and painful
• D. Well-delineated, mobile, and non-tender

Answer: (D)

Fibroadenoma is a benign, discrete breast tumor that feels like a well-defined, rubbery to firm mass and is freely movable under the skin. The hallmark is its well-delimited borders, ease of movement with palpation, and absence of pain. Because it sits separate from surrounding tissue and skin, it isn’t fixed to the skin or underlying structures, and tenderness is usually not present unless there’s concurrent inflammation. In contrast, a fixed or irregular mass raises concern for invasion, a soft, fluctuant lesion suggests a cyst or abscess, and diffuse or tender findings point toward inflammatory processes. So the best description of a typical fibroadenoma on examination is a well-delineated, mobile, and non-tender mass.
