Age of patients (years)	54.3 (SD 11.1)	45.4(11.2)	<0.0001^#
Mammographic findings	122^§	93
Microcalcifications	28	77	<0.0001^##

Noncalcified lesion	51	13
Available ultrasound findings relevant to the lesion sites	125^§§	64
Imaging size**, cm (range)	2.83 (0.3-11)	1.94 (0.24-10)	<0.0001^#
Pathologic size, cm (range)	2.88 (0.3-12)	2.15 (0.2-7.0)	0.001^#

*Lesions revealing calcifications associated with mass, focal asymmetry or architectural distortion.
**Lesion size determined by the largest diameter between mammography and breast ultrasound.
^§: 3 cancerous lesions were not shown on mammograms (false-negative).
^§§: 2 cancerous lesions were negative on ultrasound.
