Ratio of the mean variances of the tumor area and the nontumor area for different samples (normalized to the nontumor area, errors are SD, n = 4 regions from one tumor sample)

Diagnosis	Ratio of variances	Ratio of variances (>1100 nm)	Raw data (1300 nm)
Melanoma	0.45 ± 0.05	0.38 ± 0.07	0.998 ± 0.002
Nodular basal‐cell carcinoma	0.58 ± 0.07	0.55 ± 0.09	0.998 ± 0.002
Squamous‐cell carcinoma	0.40 ± 0.06	0.36 ± 0.09	1.009 ± 0.002
