There are numerous reports that the general risk of developing cancer in the breast parenchyma is elevated among women with complex fibroadenomas; these women are 3.1-3.7 times more likely to develop breast cancer than women in the general population (compared with a relative risk of 1.9 times in women with non-complex fibroadenomas). This patient had atypical lobular hyperplasia at core needle biopsy. Analyses were performed overall, within subgroups of involution status, with other demographic characteristics (age, year of biopsy, indication for biopsy, and family history), and with histologic characteristics, including overall impression [nonproliferative disease, proliferative disease without atypia (PDWA), or atypical hyperplasia]. Giant breast tumours of adolescence. When histopathology on core biopsy reveals a higher-risk lesion, such as atypical lobular hyperplasia, excisional biopsy may be indicated to rule out malignancy.
