Center for breast and thyroid cancer, led by Chan-Heun Park MD, chairman of the board of Korean break cancer research association, has successfully operated Korea's first endoscopyassisted breast cancer and thyroid cancer surgery and won an award for the best thesis from the International Society for Gynecologic Endoscopy. Endoscopy-assisted breast cancer surgery is done by an axillary and a periareolar 3~5cm incision to create working space for endoscopy to remove the tumor. With the endoscopy-assisted breast surgery, mastectomy and breast reconstruction surgery can be performed during one operation. The endoscopy-assisted surgery (EBS) achieves same result as the traditional mastectomy surgery, with minimal scar and maximum breast conservation for a positive cosmetic outcome. The EBS shortens the hospital stay down to 1 week. In recent advancement of the surgery, EBS can monitor spread of the cancer during the surgery, and can remove the tumor completely, reducing the chance of relapse. The advantage of KBSCM cancer center is the system that allows the surgery to be performed within the 2 weeks of the initial diagnosis, and “One-stop diagnostic system” that allows the patient to get all the necessary diagnostic tests on same day with minimum waiting time. The hospital offers ultrasound test, biopsy, X-ray, PET-CT, MRI, and other advanced tests in the central area in order to provide comfortable experience to the patients and family.
