Radiotherapy: Advancements, Applications, and Patient-Centered Care
Radiotherapy has become one of the most important pillars of modern cancer treatment, offering precision, effectiveness, and the ability to target tumors while sparing surrounding healthy tissues. Over the years, its evolution has been shaped by technological progress, improved understanding of cancer biology, and growing emphasis on individualized patient care. Today, radiotherapy is used in more than half of all cancer cases, either independently or in combination with surgery, chemotherapy, or immunotherapy.
At its core, radiotherapy uses high-energy radiation—often X-rays, gamma rays, or particle beams—to damage the DNA of cancer cells. Because cancer cells divide rapidly, they are more vulnerable to radiation-induced injury, leading them to die or lose the ability to multiply. A major advantage of radiotherapy is its ability to focus precisely on the tumor area, minimizing damage to healthy tissue and reducing side effects compared with older techniques.
