Radiotherapy: Advancing Precision and Hope in Cancer Care
Radiotherapy has long been one of the central pillars of cancer treatment, evolving from a basic form of localized therapy to a highly precise and technologically advanced discipline. At its core, radiotherapy uses controlled doses of high-energy radiation to destroy cancer cells, shrink tumors, and prevent the spread of malignant tissue. While the concept may sound straightforward, the science behind it is sophisticated, combining physics, biology, and medical engineering to deliver targeted therapy with increasing accuracy.
One of the defining strengths of radiotherapy is its ability to concentrate radiation directly on the tumor while sparing healthy tissues as much as possible. Modern techniques such as Intensity-Modulated Radiotherapy (IMRT), Image-Guided Radiotherapy (IGRT), and Stereotactic Body Radiotherapy (SBRT) have transformed treatment outcomes by allowing clinicians to shape radiation beams, track tumor movement in real time, and deliver doses with millimeter precision. This advancement is…
