Study Summary

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.

Primary Outcome

The investigators will evaluate changes in pathway gene expression between baseline and day 60 using NanoString NCounter platform
