Oestrogen-only HRT does not raise breast cancer risk

摘要

Postmenopausal women who take oestrogen-only hormone replacement therapy do not have an increased risk of breast cancer,according to an analysis of data from the Women's Health Initiative published last week (JAMA 2006;295:1647).These results are in contrast to the WHI trial of a combined oestrogen and progestogen product,which showed an increase in breast cancer incidence (PJ,13 July 2002,p43).
