Primary Outcome Measures:
- To determine the effect of aromatase inhibitors therapy on bone mineral density as measured by DEXA scan and compare it to the effects of tamoxifen and no hormonal therapy. [ Time Frame: once ]
Secondary Outcome Measures:
- To determine the bone fracture rate in women on aromatase inhibitors therapy and compare it to fracture rates observed in the tamoxifen and the hormone-independent group. [ Time Frame: once ]
