(Limerick East): In the first instance, I am talking about following the advice of the medical people who are running the Eccles programme. They are concerned that the issues of sensitivity, specificity and the positive predictive value of the screening would be in place. These are the terms used. Sensitivity would be a measurement of accuracy to avoid false negative results, a 90 per cent sensitivity would mean that in nine out of ten cases the results are accurate. Specificity is the same and is applied in terms of false positive results. The positive predictive value is to ensure that the proportion of people subjected to biopsy as a result of screening, in whom a malignancy is diagnosed, is not magnified by requesting people to go for unnecessary biopsies. The reason for not announcing a national screening programme is not financial, it is to ensure that as it is systematically expanded, the high quality of the results is maintained. This is the medical advice available to us. In terms of expansion I will be able to put in the region of £300,000 extra into the programme and about the same amount into the Mater programme and I hope to have it extended to at least two other areas.
