Radiotherapy Techniques

Radiotherapy techniques involve using targeted radiation to destroy cancer cells. Common methods include external beam therapy, where a machine directs high-energy rays from outside the body to pinpoint the tumor, and internal radiation (brachytherapy), where radioactive material is placed directly inside or near the cancer. Advanced techniques like IMRT or VMAT enhance precision, shaping radiation doses to minimize damage to surrounding healthy tissue. These methods are carefully planned using imaging to maximize effectiveness while reducing side effects, making radiotherapy a versatile and effective component of cancer treatment.
