Interval cancers are cancers diagnosed after a normal screening mammogram and before the next scheduled screening. Interval cancers are inherent to every screening programme. A regular review of interval cancers is important for the following reasons:
The rate of interval breast cancers in every screening unit is a key performance indicator for a breast screening programme’s effectiveness.
For education and learning purposes and continuous professional development of the screening readers, to improve the quality of the programme.
To help women diagnosed with interval breast cancer to understand their condition (1).
The screening programme’s aim is to diagnose small lesions before they become symptomatic, for better long-term prognosis and lower mortality rates. In an era of overdiagnosis and overtreatment, the ideal would be to diagnose those small cancers with potentially aggressive features (grade 3 or poorly differentiated cancers).
