Increased incidence of primary total hip replacement in rural communities: Fig 1

Abstract

two year screening interval.The proportion of true interval cancers occurring in the first two years after screening in our series was 60%, similar to that reported in the Nijmegen programme (58%) and Stockholm trial (64%) in women aged 50-64.4Recent changes designed to improve the sensitivity of the screening test are welcome, but we believe that shortening the screening interval is the only way to reduce the number oftrue interval cancers which will otherwise continue to present in the third year after screening.We thank the staff of the Manchester and Wigan breast screening services for their help in the organisation of the radiological audit and the following radiologists for their participation in the audit: J Lavelle, M Wilson, A Troop, G Kelly, and P Lane.
