Ultrasound as a Modern Cancer Therapy: Physical principles, biological mechanisms of action, and clinical applications in oncology

Ultrasound heals. What was once only a vision of the future is increasingly becoming clinical reality: sound waves, which were once used exclusively for diagnosis, are now used for therapy-precisely, gently, and biologically effectively. Physical waves become therapeutic impulses, and a diagnostic device becomes an energy platform for healing. The authors guide readers through the history and current status of this young discipline: from the first experiments in the 20th century to the breakthrough of high-intensity focused ultrasound (HIFU) and sonodynamic therapy (SDT), which triggers chemical reactions in tumor tissue. Not only are the physical principles explained in an understandable way, but also the biological and immunological mechanisms-such as how sound waves activate the immune system, make tumors "visible," and stimulate the body to heal itself. With current clinical studies, clear technological explanations, and visionary outlooks, the book shows why ultrasound not only destroys, but also regulates, stimulates, and regenerates. New research proves that ultrasound can kill tumor cells without damaging healthy tissue-and at the same time trigger immune responses that fight cancer cells systemically. In addition to clinical evidence, the book highlights technological innovations-from AI-supported control systems to 3D phased arrays and theranostic nanoparticles-and shows how the combination of physics, biology, and data analysis is shaping a new form of medicine: precise, adaptive, and humane.
