Fibroadenoma is most commonly seen in which population?

• A. Young women within 20 years after puberty
• B. Postmenopausal women
• C. Older men
• D. Infants

Answer: (A)

Fibroadenoma is most common in people who are in their teens to early adulthood, when breast tissue is still highly responsive to estrogen. The peak of incidence falls within roughly the first 20 years after puberty because estrogen stimulates the growth of breast ducts and stroma, which underlies the development of these benign tumors. After menopause, estrogen levels drop and such lesions become much less common, and they are rarely seen in infants or in men. So the classic demographic is young women within about two decades after puberty.
