Table 2. Comparison between positive and negative c-myc expression and the types of breast lesion, grouped according to benign and malignant histological results.

Types of lesion	c-myc		P
	Negative n (%)	Positive n (%)
Malignant (IDC and DCIS) Benign without atypias	14 (48.3) 40 (69.0)	15 (51.7) 18 (31.0)	0.061
Atypias (ADH) Benign	4 (36.4) 40 (69.0)	7 (63.6) 18 (31.0)	0.039
DCIS Benign without atypias	11 (55.0) 40 (69.0)	9 (45.0) 18 (31.0)	0.258
IDC Benign without atypias	3 (33.3) 40 (69.0)	6 (66.7) 18 (31.0)	0.060*

IDC = invasive ductal carcinoma; DCIS = ductal carcinoma in situ; ADH = atypical ductal hyperplasia. p-values obtained using the chi-squared frequency test. *P-value obtained using the Fisher exact test.
