The Department of Radiation Oncology is a clinical medicine which treats cancers using high-energy radiation. The Department is located on B1 of Ewha Womans University Seoul Hospital and utilizes state-of-the-art radiotherapy equipment for radiation treatment of cancer patients.
Radiotherapy can be divided mainly into internal radiation therapy and external radiation therapy. External radiation therapy uses a type of therapy equipment that emits high-energy radiation, usually utilizing a linear accelerator; this piece of radiation therapy equipment is connected to a cutting-edge computer program to minimize damages in normal tissues and irradiate maximal radiation only on the cancer region.
Recently, therapies such as intensity-modulated radiation and image-guided radiation are gaining popularity and, furthermore, a stereotactic body radiation therapy, which lowers complications and improves survival rate, has been introduced and is becoming more common.
On the other hand, internal radiation therapy involves a process of inserting a radioactive isotope mostly emitting gamma rays intracavitarily, intraductally, or inside the tissue to localize the irradiation of a high dose onto the primary lesion. This method is likely applicable to cervical cancer, endometrial cancer, etc.
