No stromal overgrowth is seen. Usual ductal hyperplasia is associated with a slight increase in risk (1.5 - 2 times) for subsequent breast cancer. We consider the term merely descriptive. Methods: From excisional biopsy or resected specimens of fibroadenoma (FA) cases treated at our institution from 2004 to 2013, we chose 46 . In analyses stratified by involution status and PDWA, complex fibroadenoma was not an independent risk marker for breast cancer. H&E stain.

Patients with complex lesions were 18.5 years older (median age, 47 years; range, 21-69 years) than patients with noncomplex fibroadenomas (median age, 28.5 years; range, 12-86 years) (p < 0.001). Jacobs. 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].
