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).

Background: To determine the cytomorphological features of complex type fibroadenoma (CFA), we reviewed fine needle aspiration (FNA) cytology with correlation to its histopathology findings, and compared them with non-complex type fibroadenoma (NCFA). The injection of sexually immature female rats with 1-methyl-1-nitrosourea results in a rapid induction of premalignant and malignant mammary gland lesions within 35 days of carcinogen administration. doi: 10.7759/cureus.12611. http://surgpathcriteria.stanford.edu/, Women with complex fibroadenomas may therefore be managed with a conservative approach, similar to the approach now recommended .

Bethesda, MD 20894, Web Policies Breast Fibroadenomas: Symptoms, Diagnosis, Treatment - Verywell Health Background Fibroepithelial lesions of the breast include fibroadenoma (FA) and phyllodes tumor (PT). Complex fibroadenomas are often smaller than simple fibroadenomas (1.3 cm compared with 2.5 cm in simple fibroadenomas). A phyllodes tumor is a very rare breast tumor that develops from the cells in the stroma (connective tissue) of the breast. Nigam JS, Tewari P, Prasad T, Kumar T, Kumar A. Cureus.
