Correct answer: B — Fibroadenoma

Fibroadenoma is the most common breast mass in adolescent females. It is benign, well-circumscribed, mobile ('breast mouse'), and rubbery. USS is the imaging modality of choice (not mammography). Most can be observed with serial USS. Excision is considered for lesions >5 cm or rapidly growing.
