A: Plots of amplitudes of selected peeks from the new group of bands at 1055, 997, 890, and 765
cm −1 appear and display a steady rise as the cancer progresses from Grade I to III. B: Plots of
amplitudes representing the quantitative analysis of amide I and amide II regions in different
cancer grades. C: Plots of the amplitudes of the gradual alteration in CH content in different
cancer grades.
