Breast Cancer Diagnosis: Tumor Identification and Localization Based on Millimeter-Wave Spectroscopy with a 33 GHz Patch Antenna

Breast cancer is one of the most common cancer types among women worldwide. Early diagnosis can enhance treatment success and survival rates. This article presents the use of patch antennas with a central frequency of 33 GHz, which provide relatively high penetration and explores the potential of millimeter-wave spectroscopy for detecting tumors in breast cancer diagnosis. Four antenna structures are placed around the breast, spaced 90 degrees apart. Three different situations are considered for the simulation; breast without tumor, breast with tumor and tumor in different positions. To associate the change of S parameters with timorous tissues more clearly, an S vector was created, and MATLAB graphics were obtained. From the S11 results obtained, it was seen that the presence of the tumor and its placement in a different location could be detected.
