HHS Vulnerability Disclosure, Help 2022 Jul;194(2):307-314. doi: 10.1007/s10549-022-06631-2. Complex fibroadenomas were diagnosed in 63 of 401 fibroadenomas (15.7%) found at consecutive percutaneous needle or excisional surgical biopsy. Objective: Breast cancer risk (observed versus expected) across fibroadenoma levels was assessed through standardized incidence ratios (SIRs) by using age- and calendar-stratified incidence rates from the Iowa Surveillance, Epidemiology, and End Results registry. FNA of CFA can lead to erroneous or indeterminate interpretation, due to proliferative and/or hyperplastic changes of ductal epithelium with or without atypia. Over time, a fibroadenoma may grow in size or even shrink and disappear. Biphasic lesions of the breast. doi: 10.7759/cureus.12611. Complex fibroadenoma is a sub type of fibroadenomaharboring one or more of the following features: Complex fibroadenomas tend to occur in older patients (median age, 47 years) compared with simple fibroadenomas (median age, 28.5 years).
