For the patients’ convenience, the breast center has been administering one-stop system by carrying out breast photography, ultrasonography, and even biopsy in case the problem was found at their visit, which has been getting a good response from patients. Besides, all things including seeing a doctor, counsel, management after operation, nutrition consultation, etc. are finished within the center.
