Specialized medical services

Director of Breast and Endocrine Surgery

We treat patients with benign and malignant mammary gland and thyroid diseases. Surgical treatment, chemotherapy, hormonotherapy, molecular targeted therapy and radiotherapy are applied to patients with breast cancer based on evidence in cooperation with plastic surgeons, radiation oncologists and medical oncologists. Sentinel lymph node biopsy, breast reconstructive surgery, and endoscope-assisted surgery are also done, achieving fewer postoperative complications and cosmetic improvement. Surgical treatment is also performed on patients with benign and malignant thyroid tumors, as well as on patients with primary hyperparathyroidism.


To prevent unnecessary axillary lymph node dissection during breast cancer surgery and consequent postoperative complications, sentinel lymph node biopsy has been performed on more than 200 patients annually. For cosmetic improvement, breast reconstructive surgery and endoscope-assisted breast surgery are actively performed (breast reconstructive surgery is done in about 40% of breast cancer surgeries). We actively conduct clinical studies for new drug development and physician-led clinical studies.
