In this study, a novel animal model for the breast cancer treatment which contains hyperthermia is proposed.For this main purpose a low cost, interstitial, bioimplant antenna by short ended single slot design is proposed to heat the cancerous tissues. Both the theoretical background of the proposed system and the simulation and measurement results of antenna design are presented. An artificial tissue phantom model has been created under laboratory conditions and then the utility of the proposed antenna has been tested on this model. Artificial tissues have been heated by 25W to (41-44 degrees Celcius) in a short time like 25 seconds. Temperature measurement is performed in real-time and wireless by a digital temperature sensor using an embedded system platform. In addition, the effectuality of the proposed hyperthermia system has been tested by the study on live mice. For this purpose, breast cancer tissues created under laboratory conditions have been transferred to experimental group Balb/c mice to induce breast cancer. According to the results of hyperthermia treatment, the breast cancer has been inhibited by the proposed hyperthermia system. All studies have been animal care with ethics committee approval. All experiments have been repeated three times by at least two observers independently. The results of this study give hope that the breast cancer treatment method using this new antenna could be used in humans in the future. For this, the number of such types of ablation studies using this type of antenna should increase.

Although the most preferred treatment methods in cancer treatment are still surgery and chemotherapy, microwave ablation, one of the minimally invasive thermal ablation techniques, is increasingly used in the clinic for patients who cannot afford the risks of these treatment methods. In this study, microwave ablation with a new NiTi ring antenna was performed on a freshly slaughtered beef liver as an Ex Vivo application. Design and optimization was carried out in the CST Microwave studio. Ex Vivo MWA application was carried out at 2.45 GHz, using 50 W microwave power for 5 minutes. The lowest width of the ablation zone formed along the x-axis was 14.58 mm, the highest width was 28.61 mm, the length of the ablation area along the y-axis was 58.032 mm, and the area of the ablation zone was approximately 5.44 cm2. These results show that the proposed NiTi ring antenna has the ability to achieve a sufficient thermal lesion in terms of ablation zone dimensions.
