Experimental and numerical study on simultaneous effects of scattering and absorption on fluorescence spectroscopy of a breast phantom

Detection of dysplastic lesions can decrease morbidity and mortality caused by cancer. The fluorescence spectroscopy is a noninvasive method of detecting dysplasia in several organs. During dysplastic progression, fluorescence intensity of spectrum is changed due to variation in absorption and scattering coefficients of tissue. In this work we have experimentally verified simultaneous effects of scattering and absorption coefficients on fluorescence intensity of different tissue like phantoms with the same optical properties as the human breast ductal carcinoma. The results are compared with those obtained by Monte Carlo simulation and good agreement between them is observed. This provides an important detecting method to discriminate dysplastic tissue from normal tissue.
