Specialist cancer centres are failing to meet waiting time targets for breast cancer investigations.
The centres of excellence are not hitting targets set by the Government, due to falling staff numbers.
Eight specialist hospitals are tasked with seeing 95pc of women referred by their GPs within a maximum period of 12 weeks.
But in one hospital, only 55pc were seen at certain periods.
The women in question, who may have cancer, are referred because they need a specialist opinion or investigation.
Bottom of the league, Waterford Regional Hospital failed to reach the standard several times during the year, seeing just 55.3pc of referrals in March.
There is no evidence that anyone suffered a delayed diagnosis despite the failure to meet the referral deadline.
