A practical guide to the management of menopausal symptoms in breast cancer patients.

Breast cancer is the most frequently diagnosed cancer in Canadian women. As a result of increased screening and improved treatment, more women are becoming long-term breast cancer survivors. However, due to either their treatment or prolonged survival, many of these women now have to face the consequences of premature menopause and prolonged estrogen deprivation. Hormone replacement therapy/estrogen replacement therapy (HRT/ERT) has, in the past, been recommended to healthy women at menopause not only for relief of short-term menopausal changes, particularly hot flashes, but also for its benefits on bone density, fracture reduction, and genitourinary symptoms. Recent studies have demonstrated that not only is HRT associated with an increased risk of developing breast cancer, but it also has been shown to increase the risk of recurrence in those with a breast cancer history. Until the safety of HRT/ERT in breast cancer patients can be more fully clarified, it would be wise to develop alternative strategies for the management of menopausal symptoms in these patients. This paper will discuss nonestrogen-based therapies for hot flashes, osteoporosis, and genitourinary symptoms, with emphasis on efficacy and safety in breast cancer survivors.
