Abstract

Raman-scattering measurements of tumor and healthy tissues are reported. The ratio of peak-intensity at 860cm<sup>-1</sup>and 1300cm<sup>-1</sup>increases from 0.37±0.01 (healthy-tissue) to 0.51±0.01 (malignant-tissue), consistent with pathological criterion of nucleus-to-cytoplasm ratio increase for infiltrating carcinoma.
