Deaths from breast cancer in Britain and the US have fallen by a quarter
since the late 1980s, report Oxford University epidemiologists in The
Lancet (vol 355, p 1822). The success is put down to earlier detection,
more prompt surgery and the use of hormonal drugs such as tamoxifen. But many
other countries are failing to use tamoxifen widely enough, according to
Christina Davies, one of the team.
