Abstract
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 (42–106Hz) 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.
