FNA of CFA can lead to erroneous or indeterminate interpretation, due to proliferative and/or hyperplastic changes of ductal epithelium with or without atypia. They fall under the broad group of "adenomatous breast lesions".. Complex fibroadenomas are often smaller than simple fibroadenomas (1.3 cm compared with 2.5 cm in simple fibroadenomas). The purpose of this study is to examine the breast cancer risk overall among women with simple fibroadenoma or complex fibroadenoma and to examine the association of complex fibroadenoma with breast cancer through stratification of other breast cancer risks.
