Abstract

In this paper, dielectric characteristics of pathological tissues cultivated using the xenograft method were analyzed. Since cancerous tissues were extracted from the nude mouse just before the measurements, they were maintained as fresh as living tissues in the measurements. This would be one of the advantages to get more accurate and reliable results. Dielectric properties of four cancerous tissues such as brain cancer, breast cancer, colon cancer and gastric carcinoma were measured in the frequency range between 45 MHz and 5 GHz. For the measurement of the dielectric properties, 58 xenografted samples were used. It was found that all of the cancerous tissues had the similar dielectric constant values. Comparing with the normal tissues, dielectric constant values of brain cancer, breast cancer and colon cancer were higher than those of the normal tissues except gastric carcinoma in the frequency range.
