Cytologic atypia in the contralateral unaffected breast is related to parity and estrogen-related genes.

Purpose: The contralateral unaffected breast (CUB) of women with unilateral breast cancer provides a model for the study of breast tissue-based risk factors. Using random fine needle aspiration (rFNA), we have investigated hormonal and gene expression patterns related to atypia in the CUBs of newly diagnosed breast cancer patients.

Methods: 83 women underwent rFNA of the CUB.
