A computer can safely replace a medical expert in a revolutionary way of interpreting a breast X-ray - according to a Cancer Research UK funded study.
A new study, published today in the New England Journal of Medicine, has shown that a single trained expert plus a computer is just as effective at detecting breast cancer as the two experts who traditionally read a mammogram in the UK.
But in the United States and some other European countries only a single expert reads mammograms. This means that single readers using the computer aided detection programme (CAD) will be even more effective at detecting breast cancer.
"The study has huge international significance," said Professor Fiona Gilbert of the University of Aberdeen and lead author of the study. "Using CAD is likely to improve breast cancer detection in those countries where only a single reader is used.
"In the UK, it will mean that the same number of experts can read more mammograms in a given period of time. We want to offer screening to a wider age group, those 47-50years old and 70-73 years old, an increase of around 30 per cent. The national programme screens over 1.7 million each year. This computer technology will help us achieve this."
The study invited around 28,000 women to have their mammograms read both in the conventional way by two radiologists and also by a single radiologist using the computer.
The results will be presented on Monday (October 6th) at the National Cancer Research Institute's annual conference in Birmingham.
Researchers found that film readers using the computer-aided detection (CAD) programme - where mammograms were read by a single expert plus the computer - was as good at finding cancers as the standard UK practice where two experts read each mammogram.
