Dr. Lorraine Doherty:

I will clarify exactly what happens in the United States, they do not have a population screening programme. What it has is a test that practitioners can offer on an annual basis to women in their practice, so it is slightly different in terms of how the programme is organised. There is not a screening programme, as such. What we have in Ireland, Northern Ireland, the UK and in other European countries is a population screening programme that is offered at regular intervals.
