A single optical fiber probe with a core diameter of 100 mu m was used to deliver visible light to tissue and from tissue to a spectrometer to diagnose cancerous tissues of different organs. Measurements were performed on brain, skin, cervix and prostate tumor specimens and surrounding normal tissues ex-vivo. The spectral slopes were positive for normal tissues and negative for the tumors. Signs of the spectral slopes were used as a discrimination parameter to differentiate tumor from normal tissues for the four organ tissues. Sensitivity and specificity of the system in differentiation between tumors from normal tissues were 93% and % 100 for brain, 87% and 85% for skin, 93.7% and 46.1% for cervix and 98% and 100% for prostate respectively.
