Fibroadenoma is the commonest solid benign lesion that can exist as a solitary mass or multiple masses in the breasts. 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.
