Variation in mammographic appearance between projections of small breast cancers compared with radial scars

Abstract

Aims: The study aims to assess variation in appearance between mammographic projections (conspicuity variation) for invasive breast cancers (IBCs) compared with radial scars (RS). Conspicuity variation has been previously described as characteristic of RS. The lesions were also compared with respect to breast density and the proportion of cases detected by one of two readers and required a third (consensus) read. Materials and methods: The study was approved by the BreastScreen Victoria research committee. Mammograms of 75 randomly selected invasive breast cancers, with histological diameter ≈10mm (IBC), were mixed with 67 consecutively detected RS, all from a double-reading population-based..
