Dr. Colm Henry:

The proportion of people who are returning is much higher since 2019. We were operating a system which had a relatively low recall rate in 2019. It has gone much higher, driven by a number of factors pertaining not just to the screening population, which is age 50 to 69, but also to some characteristics of that population and how that lends itself to interpretation of mammograms. People who know about screening who attend these screening programmes will note that the interpretation is not often binary. It is not absolute.
