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.

It should be distinguished from other benign masses of the breast by proper evaluation and management. Tumors >500 g or disproportionally large compared to rest of breast. (Sep 2005). 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. However, we cannot answer medical or research questions or give advice. invasive breast carcinoma, ductal carcinoma in situ, lobular carcinoma in situ) and atypical epithelial proliferations (e.g. ; Chen, YY.
