  Purpose
Hormone Replacement Therapy (HRT) is a double edged sword: it can alleviate the effects of menopause for a significant proportion of the female population, however for a smaller proportion, it will induce a significant increase in their short-term and lifetime risk to develop breast cancer (BC). Fewer women are prescribed HRT compared to a decade ago due to concerns pertaining to BC by both physicians and patients. By developing a technology that could identify women at risk for the adverse effects of HRT, during the first few months of its use, physicians may offer HRT to a wider proportion of the female population during menopause. More importantly, as it relates to BC prevention, such a technology will identify women at risk and provide a useful decision making tool regarding their care during the menopausal years.

Study Population
Post-menopausal women attending the Endocrinology Clinic at St. Michael's Hospital (Toronto, Ontario, Canada) who have elected to undergo a 1-year HRT regiment but had no prior HRT treatment. The comparison group (control) will comprise of post-menopausal women not on HRT and had no prior HRT treatment. Controls will be recruited among women at the University Health Network or attending the Endocrinology Clinic at St. Michael's Hospital (Toronto, Ontario, Canada).
