Cancer is one of the most studied pathology and early detection could be helpful for treatment or other types of interventions that may stop the fatal evolution. The preclinical studies can be applied on experimental models, especially on rodents. Cancer can be induced experimentally most often by the application of chemical carcinogens, tumor cells inoculation or xenografts. FT-Raman spectroscopy in conjunction with the surface enhanced Raman scattering (SERS) has been applied for preliminary investigation on skin tissue from mice models in order to evaluate the possibility to record analytical spectral fingerprint in tissue diagnostic. FT-SERS spectra from the UV and chemically damaged tissues showed dominant characteristic bands from collagen and nucleic acids, whereas the bands attributed to proteins are observed with less extent.
