	If, even after [[consultation]], it is not clear whether a tumor is a fibroadenoma or phyllodes tumor, then it can be reported as a '''cellular fibroepithelial lesion''' or a '''fibroepithelial neoplasm'''. A benign lesion that resembles but does not clearly show a fibroadenoma can be called a '''fibroadenomatoid lesion'''.
