Introduction
Microwave Imaging (MWI) is a promising non-invasive technology utilized for breast cancer detection. This method leverages the differences in dielectric properties between healthy and malignant tissues, creating potential for early detection as well as detailed tissue characterization. The growing interest in this technique has led to the development and compilation of various datasets that support research and innovation in the field. In this document, we present a comprehensive review of the most relevant datasets available for breast cancer detection using MWI. These datasets serve multiple purposes, including algorithm testing, validation of imaging methodologies, and training of machine learning models for automatic tumor detection.
