Dr. Lim contrasts historical four-field box radiation with contemporary IMRT, CT-based planning, daily cone-beam verification, and AI-assisted contouring with dosimetrist support. They review pelvic radiation treatment timelines, emerging hypofractionation data, and the essential role of image-guided brachytherapy for cervical cancer, including outpatient workflows and improved tumor coverage with reduced bladder/rectum dose. The group covers patient counseling on expected side effects, radiation-induced menopause, fertility, sexual health, vaginal stenosis prevention with dilators/pelvic floor therapy, late effects, re-irradiation considerations, spacers, palliative regimens, and stereotactic radiosurgery/Gamma Knife for brain metastases.
