At a mean follow-up of 2 years, we found a low incidence of malignancy in complex fibroadenomas. The average fibroadenoma is anywhere from the size of a marble up to 2.5 centimeters (cm) in diameter. He Q, Cheng G, Ju H PLoS One 2021;16(7):e0253764. Most present in adults between menarche and menopause.

No apparent proliferative activity is present. Four variants are described by the Washington Manual:[7], Considered a variant of fibroadenoma by many authorities:[8], Breast - Tubular Adenoma - low power (SKB), Breast - Tubular Adenoma - medium power (SKB), Breast - Tubular Adenoma - high power (SKB), Breast - Tubular Adenoma with lactational change (SKB). They fall under the broad group of "adenomatous breast lesions".. Complex fibroadenomas are often smaller than simple fibroadenomas (1.3 cm compared with 2.5 cm in simple fibroadenomas). Dupont WD, Page DL, Parl FF, Vnencak-Jones CL, Plummer WD Jr, Rados MS, Schuyler PA. Up to 66% of fibroadenomas harbor mutations in the exon (exon 2) of the mediator complex subunit 12 (MED12) gene.
