Introduction and Objectives: The response of the breast tissue including glandular and fat cells, milk ducats and blood vessels to nearinfraredlight source were studied. Any changes of absorption can be as a prognosis assay in breast tissue.Methods: The study was performed on samples of water, milk, fat, oxygenated hemoglobin using a spectrometer (USB4000 Fiber OpticSpectrometer, USA) and near-infrared light source from LED (Phwee). The experimental material inserted in to the main and minorblood vessels which arranged in the breast phantom.Results: A specific change in the optical density of the components of the breast tissue was observed. The absorption values wereobtained for hemoglobin oxygenation: 1.12, water: 0.7, Milk: 1.07 and fat: 0.8.Conclusion: This method can be used to check the different values of accountability, increased hemoglobin levels in cancerous tissue.Even breastfeeding mothers suspected to breast cancer can use this invasive and safe method for presentation of distribution of bloodvessels and milk ducts.
