BreastCheck screening will not resume until September and will see an initial 80,000 paused appointments seen first, according to the Chief Clinical Officer at the Health Service Executive, Dr Colm Henry.
Speaking on RTÉ's Today with Sarah McInerney, Dr Henry said there are difficulties in re-purposing BreastCheck mobile units for the Covid-19 environment.
As a result, he said, it is likely to delay the screening further and move it from a two-yearly to a three-yearly check for women.
It comes as the cervical screening services reopen today, which will see a backlog of an initial 100,000 women seen before October and a further backlog until February 2021.
