Infrared radiation for cancer hyperthermia: the light to brighten up oncology.

Introduction: Cancer constitutes the greatest public health threat to humans, as its incidence and mortality rates continue to increase worldwide. With the development of medical physics, more practitioners focus on the direct and indirect anti-tumor effects of physical factors. Infrared radiation (INR) is currently the most rapidly developing physical therapy method for tumors and has become a favored target for many oncologists and researchers owing to its advantages of high efficiency, low toxicity, and strong feasibility.

Areas covered: This work provides a comprehensive collection of the latest information on INR anti-tumor research, drawing from public medical databases (PubMed, Web of Science, Embase, and Clinical Trials) from the last 10 years (2014 to 2024), and encompassing both basic and clinical research in oncology and physics. This article reviews the application of INR in tumor hyperthermia, summarizes and analyzes the practical value of INR for tumor treatment, and discusses future development trends to provide valuable assistance for the subsequent development of oncology.

Expert opinion: Currently, INR has continuously accumulated excellent data in the field of tumor hyperthermia, bringing practical survival benefits to patients with cancer, and playing an important role in basic and clinical cancer research.
