We can confirm the hypothesis that there exists a relationship between the time since last negative screen and the biological aggressiveness of interval-surfacing cancers. The second interval year, but not the first, was associated with an excess risk of lymph node metastases that was independent from tumour size and grade. The results of this study improve the understanding of the screening process, particularly the interplay between mammography sensitivity and the natural history of breast cancer.

More ‘informed’ review is more likely to yield an IC classification as MS or SE. Due to expected variability, review methods need standardisation to improve screening quality. Our data support blinded review of IC in mammography screening.
