But female cancer deaths are still the thirdhighest in Europe. Breakthrough Breast Cancer's research suggests this may be partly down to GPs failing to refer patients to hospital soon enough. Breast cancer, the most common female form of the diseaseaffects more than 34,000 women a year. The charity says 42 per cent who go on to be treated are not referred to hospital urgently. The calculations are based on records from the Department of Health and the Commission for Health Improvement, the NHS standards watchdog.
