Monitoring of Breast Tissue Change Due to Hormone Replacement Therapy in Post-menopausal Women Using OBS (TiBS-HRT)
Recruitment status was Not yet recruiting
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.
