PCNA & TUNEL.

	PCNA	TUNEL

Benign lesions	3.8 ± 2.5^a	0.19 ± 0.02^a
in situ carcinoma	19.2 ± 5.5^b	1 ± 0.4^b
Infiltrating carcinoma	23.8 ± 5.6^c	1.5 ± 0.5^b

PCNA & TUNEL analysis were measured as average optical density ± SD. Values denoted by different superscripts are significantly different from each other. Those values sharing the same superscript are not statistically different from each other. Statistical analysis refers to each antibody separately. Significance was determined by multiple comparisons by the Fisher test at p ≤ 0.05.
