I propose to take Questions Nos. 261 to 263, inclusive, together.
Prior to its introduction on a national scale, digital mammography was introduced on a pilot basis in Ireland. Based on the success of the pilot, BreastCheck transferred to digital mammography. Digital mammography gives enhanced image quality with improved visualisation of dense breast tissue. It allows images to be acquired more quickly and enables the manipulation of images to obtain better detail. Digital mammography also involves a significant reduction in the radiation dose associated with screening examinations.
A research study sponsored by the US National Cancer Institute, Digital Mammographic Imaging Screening Trial (DMIST), provides evidence to support the efficacy and safety of digital mammography. BreastCheck continues to review all relevant research as it is published. The extensive independent breast screening review for the United Kingdom (Marmot Review) published in 2012 demonstrated that breast screening leads to a reduction in mortality.
A clinical trial on digital mammography has not been carried out in Ireland.
