Description of intervention(s) / exposure
This trial aims to assess the utility, through DEXA scans and biochemical markers of bone turnover, of a strategy of monitoring and intervention with oral alendronate in postmenopausal women with hormone-receptor positive breast cancer receiving five years of adjuvant anastrozole. It specifically addressed the issues of osteopaenic and osteoporotic women in this setting and will test three years versus five years of alendronate use.
