This article is dedicated to assisting healthcare professionals in promptly identifying and examining patients displaying symptoms that might indicate bladder and kidney cancer. Recently, wearable antennas have garnered significant attention from researchers and gained widespread popularity owing to their appealing features and potential applications. They are essential to wireless body area networks used in sports, healthcare, the military, and identity. Unlike traditional antennas, these devices are in immediate contact to the human body’s tissues, meaning that parameters such as gain, radiation pattern, bandwidth, return loss, directivity, efficiency, and specific absorption rate (SAR) are all impacted by interaction of human body tissues. The goal is to use the understanding of microwave signal interaction with bodily tissues to identify and pinpoint kidney cancers. When compared to healthy tissues, malignant tumors frequently display different dielectric characteristics. These dielectric properties, such as permittivity and conductivity, influence how tissues interact with electromagnetic waves. Microwave techniques have the potential to offer diagnostic information without the necessity for invasive surgical procedures. In this study, we develop metamaterial surfaces that offer a high degree of isolation and greatly lower SAR, with goal of improving the performance and minimizing any negative impact. The paper provides thorough analysis of the requirements and analytical elements pertinent to wearable antennas, such as SAR for on-body evaluation,
