[Estrogen replacement in women treated for breast cancer]

Oestrogen replacement therapy in women with a history of breast cancer has long been considered contraindicated. However, the literature does not indicate an increased risk of recurrent breast cancer in postmenopausal women receiving oestrogen replacement therapy. We advocate that women with a history of breast cancer without nodal involvement could be offered oestrogen replacement therapy and thereby benefit from prevention of cardiovascular disease and osteoporosis. But the patients must accept a potentially increased risk of recurrence. We emphasize the need for randomized prospective studies.
