The annual report from the national breast screening programme has indicated there has been a 19% increase in uptake of the service.
BreastCheck has been in operation since February 2000.
Almost 60,000 women attended mammogram appointments with BreastCheck in 2005. It is the highest figure in the programme's history and 318 cancers were detected during the year.
However, rollout continues to be an issue. Although BreastCheck is a national screening programme it is not available nationwide.
Currently screening is available in large parts of the northeast, midlands and east, while services commenced in Kilkenny last May.
Work is under way on new screening facilities in Cork and Galway. It is expected they will be in operation by the end of autumn next year.
BreastCheck Director Tony O'Brien has said national roll-out is on target.
However, Fine Gael's Health Spokesperson Dr Liam Twomey said roll-out is behind and as a result lives are being put at risk.
Dr Twomey said mortality rates from cancer are higher in areas not covered by the service. Fine Gael has called on the Government to increase resources to help speed-up roll-out.
