Figure 3. Relationship between optical parameters and benign breast composition with differences in breast density.

A) Parameter maps from a low density margin; B) Parameter maps from a high density margin; blue indicates higher values of the corresponding variable. C) eCDFs of all measured sites from negative, neoadjuvant-naïve margins, separated by mammographic breast density. P-values were calculated with modified Kolmogorov-Smirnov statistics.
