Table 1.

Tumour characteristics of patients 1–3: histological diagnosis and tumour type; classification of mammographic breast density according to the American College of Radiology (ACR); preoperative imaging according to the Breast Imaging Reporting and Data System (BIRADS); dimensions and weight of the breast samples; maximum tumour size according to histopathology; TNM classification

Patient	Histological diagnosis	ACR	BIRADS	Sample dimensions and weight	Histological maximum tumor diameter	TNM
1	Multifocal invasive carcinoma of no special type (NST, formerly invasive ductal), G1	II	IV	16.5 × 10.5 × 9 cm3 501 g	40 mm	pT2(m) pN1a (1/16) Mx
2	Trifocal invasive carcinoma of no special type (NST, formerly invasive ductal) and invasive lobular carcinoma, G1–2	II	IV	25 × 18 × 4.5 cm3 1009 g	15 mm	pT1c (trifocal) pN2a (7/16) Mx
3	Bifocal carcinoma of no special type (NST, formerly invasive ductal) G2	II	V	26 × 13.5 × 2.5 cm3 570 g	25 mm	pT2(m) pN0 Mx

Note that the smallest sample diameter is measured in antero-posterior direction and does not correspond to the maximum craniocaudal diameter used for the experimental mammography
