Design and phototyping of an early breast cancer detector using bio impedance measurement

Abstract

Breast cancer remains a significant global health concern, emphasizing the need for effective and cost-effective early detection methods to improve patient outcomes. This research design and prototyping of a breast cancer early detection system by utilizing electrical bio-impedance technology. Electrical bio-impedance involves measuring the resistance and reactance of breast tissue to small electrical currents, providing valuable insights into tissue composition and structure. The proposed system incorporates electrodes placed on the breast surface to deliver low-frequency electrical currents of 20,434 Hz and 0.5 mA to measure the resulting impedance and phase angle. By analyzing the resulting impedance and change in phase angle, characteristic patterns associated with healthy and cancerous breast tissue can identified. When the difference between right breast impedance and left breast impedance is beyond 4187 Ω, a device warns the user of cancer risk. The breast cancer early detector prototype designed to be non-invasive, portable, and cost-effective, making it suitable for widespread screening in clinical and community settings. Due to the standardized protocol for testing medical equipment, initial testing done on rabbit. Preliminary testing (preclinical testing) demonstrates promising results, indicating that the proposed method can greatly affect the detecting breast cancer at early stages. Further validation through largescale clinical trials is necessary to assess the system's sensitivity, specificity, and overall effectiveness in realworld applications. If successful, this technology could significantly enhance current breast cancer screening practices and contribute to improved patient outcomes.
