Electrical impedance analysis of biopsy specimens to distinguish healthy and cancerous breast tissues

One of the most common cancer types in the world is breast cancer. Screening and diagnostic methods like mammography, ultrasound or magnetic resonance imaging are not enough for all clinical situations to conclude about the exact nature of the lesions found in the breast tissue. Therefore, physicians need biopsy as an invasive procedure. The aim of this study was to investigate the electrical impedance of abnormal and normal breast tissue, in order to find a new method, for reliable, non-invasive detection of breast cancer. For this purpose, breast tissues taken from five patients were provided Bezmialem Vakif University Faculty of Medicine Department of General Surgery, and impedance measurements have been done at the Pathology Department of the same university. Impedances of healthy and tumoral tissues for each patient were measured. Analysis of impedance values has shown significant difference between healthy and tumoral tissues.
