With annual visit of 120,000 patients with breast diseases, the Center integrates professional groups of breast surgery, breast oncology and radiation oncology as basis, combining with related groups such as pathology, radiology, ultrasound, and nuclear medicine. The Center is built on the new "disease-centered" treatment concept.
