The National Screening Service in the HSE have advised that BreastCheck delivers its services in line with international criteria for screening programmes, based on the best international evidence.
They note that breast density measurement is not used in any population-based breast screening programme internationally, as there is no evidence to support improved overall outcomes for the population. In addition, there is no accepted standardised way of measuring breast density or international guidance to be given to women and no specific action that can be taken.
The NSS and BreastCheck monitor new research regularly to review for any potential changes or improvements that can be made: however, the situation in relation to breast density is not expected to change in the foreseeable future.
It is important to understand that breast screening does not prevent breast cancer. However, it helps to find breast cancer at an early stage. A small number of cancers cannot be found by a mammogram, but attendance for regular screenings means that many changes can be found as early as possible.
It is also important to emphasise that BreastCheck is a screening service for otherwise well women with no symptoms. Any woman, regardless of age or eligibility with BreastCheck, who has any concerns relating to their breast health should contact their GP immediately to discuss their concerns.
Any proposed future changes to national population-based screening programmes will be assessed by the National Screening Advisory Committee, which was established in 2019. The Committee’s role is to undertake an independent assessment of the evidence for screening for a particular condition against internationally accepted criteria and make recommendations accordingly.
The addition of any new population-based screening programmes, or modifications to existing programmes, will be incorporated as part of the Committee's work programme following a robust, methodologically sound and detailed analysis of the evidence in each and every case against internationally accepted screening criteria.
