Radiation Oncology is a highly specialized field that treats malignant tumors and some proliferative diseases with ionized radiation, and encompasses clinical oncology, radiobiology and radiophysics. Radiation therapy is one of three major anti-cancer treatment modalities along with surgery and chemotherapy. Approximately one third to one half of all cancer patients have received curative or symptomatic radiotherapy. The most powerful benefit of curative radiotherapy is cancer cure and preservation of organ function or cosmesis together, which can be evident of cancers in the breast, lung, gastrointestinal tract, head and neck, limbs, brain, genitourinary tract, and non-Hodgkin¡¯s lymphoma. Palliative radiotherapy is delivered to metastatic tumors on the brain, bone, lymph nodes, and other oncologic emergency conditions. The goal of radiation therapy is to eradicate or shrink the tumor cells without damaging the surrounding normal tissues. To achieve this, treatment plans are created using the most advanced computing and imaging techniques, and the Department of Radiation Oncology makes every effort to increase the cancer cure rate and to improve the quality of life through basic oncologic and clinical research.

The Department of Radiation Oncology of Kyung Hee University Medical Center offers the special radiation treatment such as three dimensional conformal radiotherapy, intensity modulated radiotherapy, image-guided radiotherapy and tomotherapy-the most newest radiotherapy technique.
