Breast Cancer Detection Using Microwaves by Changing the Electrical Properties of Tissues

Abstract

Worldwide, breast cancer is one of the leading causes of death among women. However, effective treatments are available for this type of cancer if diagnosed early. The difference in electrical properties between normal and malignant breasts is the basis for detecting the tumor and its location; in this article, the tumor is detected based on the change in conductivity and permittivity values in tissues between the two cases if a tumor is present and if it is not. In this paper, CADFEKO 2018 was used to simulate a design composed of hemispherical breast tissue and two dipole antennas, one of which transmits and the other receives a signal. There is a difference between the results of a breast design that contains a tumor and a design that does not have a tumor, as shown by preliminary simulations and the results of the designs themselves. Thus, by analysing these outcomes and simulation-generated signals, we can determine whether a tumor exists or not.
