FT-Raman spectra and dielectric properties of benign and malignant women breast tissues in vitro were investigated. FT-Raman spectra for the malignant tissues showed a remarkably decrease in the lipid/protein ratio. Dielectric properties of women breast tissues measured in the low frequency range (42-10(6)Hz) were interpreted in spite of electrode polarization effect. Experimental results showed a contrast between the dielectric properties of malignant (Grade II) and benign tissues within the frequency range studied. The permittivity of malignant to normal breast tissue was found to be 160:1 while it could be 1.3:1 for fibrocystic breast tissues. These findings could contribute to distinguish between two breast tissues. The differences in spectral features between benign and malignant tissues may lead to breast cancer detection.

Raman Spectroscopy: Overview

The underlying principle of Raman spectroscopy is based on the interaction between light and matter, specifically molecules' inelastic scattering of photons. When a monochromatic beam of light, typically from a laser source, interacts with a sample, most scattered light has the same frequency as the incident light. This is known as Rayleigh scattering.
However, a small fraction of the scattered light exhibits a frequency shift due to the exchange of energy between the incident photons and...
