    "abstract": "Wavelet transform of polarized fluorescence spectroscopic data of human\nbreast tissues is found to reliably differentiate normal and malignant tissue\ntypes and isolate characteristic biochemical signatures of cancerous tissues,\nwhich can possibly be used for diagnostic purpose. A number of parameters\ncapturing spectral variations and subtle changes in the diseased tissues in the\nvisible wavelength regime are clearly identifiable in the wavelet domain. These\ninvestigations, corroborated with tissue phantoms, indicate that the observed\ndifferences between malignant tumor and normal samples are primarily ascribable\nto the changes in concentration of porphyrin and density of cellular organelles\npresent in tumors.",
