On mammography a mass is defined as a space occupying lesion, visible in two different projections, characterised by its shape and contour. This is to be distinguished from the asymmetric density which corresponds to a localised asymmetry without a defined contour and has a gradual density change at the margins. The smaller the lesion, the harder it is to characterise and therefore there is a lower threshold for intervention. A small mass is defined as 10mm or less in size for the purposes of this paper.
