What is the primary appearance of a fibroadenoma on physical examination?

A fibroadenoma typically presents as a firm, mobile mass on physical examination. This characteristic is an important differentiating factor in breast lump evaluation. Fibroadenomas are benign breast tumors composed of glandular and stromal tissue, which give them their well-defined, rubbery feel. Because of their mobile nature, they can be easily moved under the skin when palpated, a feature that distinguishes them from other types of breast lesions, such as cysts or malignant tumors, which may be more fixed.

The firmness indicates the dense tissue composition, and the mobility suggests that it is not tethered to the surrounding structures or skin. This appearance is critical for clinicians when they assess breast lumps, as it guides the diagnostic approach and helps determine the need for further imaging or biopsy.

The other descriptions invoking warmth, tenderness, softness, or inflammation do not align with the typical physical examination findings of a fibroadenoma. Instead, those characteristics may suggest other conditions such as infections, abscesses, or malignant changes, which would require different management strategies.
