British Menopause Society consensus statement: The risks and benefits of HRT before and after a breast cancer diagnosis.

Abstract

In women at population risk of breast cancer (i.e. most), short-term exposure to hormone replacement therapy (i.e. up to five years' use) for symptom relief exceeds its potential harms, including the associated, increased risk of breast cancer diagnosis. Many women and health care professionals, however, consider this to be unacceptably high, although the degree of risk conferred appears equivalent to, or less than that of, other lifestyle risk factors for this condition. In contrast, it is recommended that symptomatic women at high baseline risk due to a family history or a biopsy-confirmed high-risk benign breast condition and those with previous breast cancer should be managed initially with lifestyle changes and non-hormonal alternatives. In a minority, whose symptoms are refractory, hormone replacement therapy and or topical estrogen can be considered but prescription should only take place after a discussion between the patient, her primary health care and breast specialist teams.
