Modelling and characterization of cell abnormality using electrical impedance spectroscopy (EIS) system for the preliminary analysis to predict breast cancer

In Bangladesh, breast cancer accounts for 69% death of women. This number increases day by day due to unawareness of the people, lack of confidence about medical treatment, improper screening, maltreatment and lack of motivation to go for institutional treatment and management. The most common form of detection mechanism for breast cancer available to the mass people is mammography, however, several risks, such as direct exposure of radiation are associated with it. Mammography tests are also quite expensive which cannot be readily availed by the mass population of the country. Electrical Bio-impedance (EBI) analysis can be used in breast cancer detection and screening. When EBI measurements are taken at various frequency points it is called Electrical Impedance Spectroscopy (EIS) which can be used as a locally available and cheap screening tool for breast cancer detection. This paper uses an established model of a biological tissue to study the effectiveness of an EIS device that can be constructed with simple electrical components available locally. The impedance and phase angles of both models of normal tissue and cancerous tissue were measured and compared with a known reference. Results showed that the EIS device works satisfactorily and with fine-tuning, will provide the necessary medical facility at an affordable cost.
