There are numerous reports that the general risk of developing cancer in the breast parenchyma is elevated among women with complex fibroadenomas; these women are 3.1-3.7 times more likely to develop breast cancer than women in the general population (compared with a relative risk of 1.9 times in women with non-complex fibroadenomas).

Mousa-Doust D, Dingee CK, Chen L, Bazzarelli A, Kuusk U, Pao JS, Warburton R, McKevitt EC. 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. 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). The term fibroadenoma combines the words "fibroma," meaning a tumor made up of fibrous tissue, and "adenoma," a tumor of gland tissue. Careers. Become a Gold Supporter and see no third-party ads.
