Radiotherapy: Precision Treatment in Modern Cancer Care
Radiotherapy is a cornerstone of modern cancer treatment, offering a targeted approach to destroy cancer cells while preserving surrounding healthy tissue. It involves the use of high-energy radiation to interfere with the DNA of cancer cells, preventing them from multiplying and ultimately leading to cell death. Unlike systemic treatments such as chemotherapy, radiotherapy acts locally, making it an essential tool for controlling tumors in specific areas of the body.
The process of radiotherapy begins with careful planning. Imaging technologies such as CT, MRI, or PET scans help doctors determine the exact location, shape, and size of the tumor. This information allows radiation oncologists to design a treatment plan that maximizes the dose to cancer cells while minimizing exposure to healthy tissues. Advanced techniques like intensity-modulated radiotherapy (IMRT) and stereotactic body radiotherapy (SBRT) have significantly increased the precision and effectiveness of this therapy.
