While cancer detection did not differ in women screened with screen-film mammography (SFM) or digital mammography (DM), the recall rate and false-positive risk were lower with DM than with SFM after adjustment was made for the woman's screening mammogram, radiology unit screening round, age at screening, and time trends

One-third of malignancies detected on the basis of calcifications only are invasive cancers. They tend to be smaller but not less aggressive than invasive cancers detected on the basis of other features. 

Compared with published results of analog screening, digital screening offers the potential to increase the rate of invasive cancers detected on the basis of calcifications in population-based mammographic screening.  Digital mammography has the potential to increase the rate of invasive cancers detected on the basis of isolated calcifications---cancers that tend to be smaller than those discovered because of other radiologic features

The results of this study show that recall rates and the rates of invasive tests performed were lower in the digital mammography group than in the screen-film mammography group, whereas no significant differences between the groups were observed for the overall cancer detection rate
