The electric conductivity has shown its potential to differentiate benign and malignant breast tissue. We investigate the correlation between the electric conductivity with known prognostic factors of invasive breast cancer using the electric properties tomography reconstruction algorithm and multi-receive coil combined technique. Breast cancers with the established poor prognostic factors (axillary lymph node metastasis, lymphovascular invasion and high histologic grade) showed higher conductivity value than those without. Our results show the possibility that the electric conductivity can be differentiated according to the known prognostic markers in invasive breast cancers.
