Paper Abstract

Recent advancements in the technique of Raman spectroscopy now make it possible to achieve rapid, minimally invasive and non-destructive characterization of tissues. In order to evaluate the efficacy of this technique for diagnosis, the Raman spectra of normal and neoplastic human tissues (e.g., breast, kidney, liver and colon) were obtained utilizing visible and near-IR excitation. Normal breast tissue and colon adenocarcinoma showed major Raman features due to the presence of carotenoids and lipids. In breast carcinoma, the features due to lipids were attenuated and as fibrosis (desmoplasia) increased, new spectral features attributable to collagen were observed. Samples of normal and neoplastic liver and kidney show unique spectral differences sufficient to permit tissue differentiation.
