A new perspective on radiotherapy in the comprehensive treatment of cancer

Abstract Radiotherapy (RT) has become an indispensable part of modern cancer treatment owing to its efficacy, precision, and safety. With continuous advances in clinical practice, the role of RT in comprehensive cancer treatment has been repositioned. Through a combination of chemotherapy, targeted therapy, and immunotherapy, RT can achieve multiple therapeutic goals, including disease cure, symptom relief, improved quality of life, and prolonged survival. Therefore, understanding the development of RT, its mechanisms, technological innovations, combined therapeutic strategies, and prospects is essential for advancing tumor treatment and improving patient survival.
