Clinical vignette presents a 24-year-old woman with a short-duration, firm, round, mobile 2-cm palpable breast mass in the superior outer right breast quadrant. Regular menses with recent combined estrogen/progestin oral contraceptive use and a history of estrogen exposure are emphasized, alongside family history of breast cancer. The question and explanation guide diagnosis toward fibroadenoma, a benign estrogen-sensitive lesion common in women under 30, typically well circumscribed and mobile. Alternative causes such as malignancy, fat necrosis, and fibrocystic changes are contrasted by key features like mobility, shape, laterality, and typical presentation pattern.
