Histological Scoring

		Id-1	Id-2	Id-3
Normal (n = 6)	Ductal cells	2.0 ± 0.4	2.3 ± 0.2	2.5 ± 0.9
Cancer (n = 10)	Cancer cells	4.5* ± 0.5	5.2§ ± 0.3	4.5 ± 0.6
CP (n = 9)	Typical CP lesions (n = 9)	2.7 ± 0.5	3.1 ± 0.6	3.4 ± 0.7
	Dysplastic ducts (n = 4)	5.3† ± 0.2	5.8‡ ± 0.2	5.3 ± 0.4
	Atypical papillary ducts (n = 5)	4.4‡ ± 0.2	5.2‡ ± 0.2	5.0 ± 0.4

Scoring of the histological specimens was performed as described in the Patients and Methods section. Values are the means ± SD of the number of samples indicated in parenthesis. P values are based on comparisons with the respective controls in the normal samples.

*, P < 0.02; ^†P < 0.01; ^‡P = 0.004; ^§P = 0.001.
