    FIGURE 1. Average S3 of cancerous (solid) and normal (dash) breast tissues acquired by the selective Δλi = 40 nm: The salient difference of S3 between cancerous and normal breast tissues can be observed as two reverses of the peak intensities at ~294 and ~340 nm, and a tiny peak is evident at 385 nm for the cancerous tissue.
