These tumors are usually benign, but they can come back and cause the breast to look abnormal if not totally removed.

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. //--> The pictured lesion is sclerosing adenosis, a benign breast lesion characterized by expansion of glands (with preserved 2 cell layers: inner epithelial and outer myoepithelial cells) within the terminal duct lobular unit with distortion by fibrosis / sclerosis.

A benign gland has two cell layers - myoepithelial and epithelial. FNA of CFA can lead to erroneous or indeterminate interpretation, due to proliferative and/or hyperplastic changes of ductal epithelium with or without atypia. Women with complex fibroadenomas may therefore be managed with a conservative approach, similar to the approach now recommended .
