OBJECTIVES: Primary * Determine whether the genomic profiles of breast epithelial cells of high-breast cancer-risk women, as defined by their positive BRCA1 status and nulliparous condition, express a signature indicative of high-risk. Secondary * Determine whether women identified to express a "high-breast cancer-risk" signature will revert it to a "low-risk" signature after a 90-day treatment with r-hCG, which should have induced breast differentiation and genomic changes that would serve as biomarkers indicative of decreased breast cancer risk. OUTLINE: Patients receive recombinant human chorionic gonadotropin subcutaneously three times weekly. Treatment continues weekly for 90 days in the absence of unacceptable toxicity. Benign breast tissue specimens are collected by core needle biopsy at baseline, day 90, and day 270. Tissue samples are analyzed by cytopathology for epithelial normality, Ki67 immunohistochemical staining for cell proliferation, cDNA microarray for gene expression, and serum studies for hormone levels and biomarker determinations. After completion of study treatment, patients are followed for 24 weeks.
