The sharp drop in breast cancer rates in the United States reported last week is astonishingly good news. It is the first major reduction in the incidence of a malignancy that strikes more than 200,000 American women every year — and kills some 40,000 annually.

This is extraordinary news. For the first time incidence in breast cancer is declining massively, by 7 per cent. It seems likely that is linked to the declining use of hormone replacement therapy. Which all goes to show that if we can understand the causes, then we can begin to tackle this disease.
