Dramatic bone loss in women during the first five years following cessation of ovarian function has been well documented (1). It is estimated that greater than 1.5 million fractures related to osteoporosis (OP) will occur in the US annually (2) and that 33% of women will have sustained hip fractures by age of 90 years(3). With increasing age also comes increasing risk of many cancers, including ovarian, uterine, breast, lung, and colon cancers. 23,500 new cases of ovarian cancer and 38,400 new cases of uterine cancer were diagnosed in the US last year (4). Many of these patients are postmenopausal at the time of diagnosis, and many enter menopause secondary to surgical resection of the ovaries or chemotherapy prompting ovarian failure. This population of women therefore, is at significant risk for osteoporosis.
