Comparison of conventional ultrasonographic features of lesion location of patients in the two groups [n (%)].

Group	Cases	Irregular morphology	Unclear boundary	Uneven echo	Micro-calcification	Side-acoustic images
MTG	106	100 (94.34)^a	77 (72.64)^a	76 (71.70)^a	73 (68.87)^a	70 (66.04)^a
BCG	50	3 (6.00)	2 (4.00)	3 (6.00)	1 (2.00)	2 (4.00)
χ²		118.195	64.041	58.666	60.924	52.614
P-value		<0.001	<0.001	<0.001	<0.001	<0.001

P<0.01, compared with BCG. MTG, malignant tumor group; BCG, benign control group.
