A robust knowledge of how to reduce breast density could play a key role in breast cancer prevention in premenopausal women, but viable preventative targets to reduce breast density-associated breast cancer risk are yet to be developed. The investigators propose to investigate the effect of RANKL inhibition with denosumab on breast tissue markers in high-risk premenopausal women with dense breasts. Study findings could provide robust evidence to move forward with a clinical trial targeting RANKL inhibition in premenopausal breast cancer prevention.


Inclusion Criteria: - Female. - Premenopausal. - At least 35 years of age. - Dense breasts on routine mammogram. - Willing to take calcium (1,200mg) and vitamin D (800 IU) daily. - At increased risk for breast cancer using any of the following: - Positive family history of breast cancer - Breast cancer risk prediction models - Able and willing to return for repeat biopsy. - Able to understand and willing to sign an IRB-approved written informed consent document. Exclusion Criteria: - Current use of tamoxifen, aromatase inhibitors, or bisphosphonates. - Concurrently participating in another cancer chemoprevention trial (unless no longer receiving the intervention). - Pregnant or lactating. - Recent tooth extraction or dental procedure. - Unhealed and/or planned dental/oral surgery. - History of osteonecrosis/osteomyelitis of the jaw. - History of osteoporosis or severe osteopenia. - Unable/unwilling to return for repeat biopsy.
