It is a great honor to assume the presidency of the Japanese Society of Oncoplastic Breast Surgery (JOPBS). I am Hiroki Mori from the Department of Plastic and Reconstructive Surgery at the Institute of Science Tokyo. I am committed to building upon the achievements of my predecessors and contributing to the continued growth and development of our society.

Since its establishment, JOPBS has played an important role in the registration and management of breast tissue expanders and implants, as well as in monitoring associated complications. In recent years, the society has evolved into a forum for discussing a wide range of issues related to breast cancer surgery. In addition to breast and plastic surgeons, physicians from other specialties and healthcare professionals, including nurses, have become increasingly involved in our activities. I believe that our mission is to pursue both oncological safety and aesthetic outcomes, while supporting patients through multidisciplinary collaboration so that they can maintain their quality of life and live fulfilling lives after breast cancer treatment.

To achieve this mission, strengthening collaboration between breast surgeons and plastic surgeons is essential. From improving aesthetic outcomes in breast-conserving surgery to breast reconstruction following mastectomy, closer cooperation and shared decision-making between these specialties will allow us to offer patients a broader range of treatment options.

Another important priority is to further promote breast reconstruction and reduce regional disparities in access to care. Although breast reconstruction has become more accessible through the expansion of insurance coverage, patients should have access to appropriate information and treatment options regardless of where they live. We will continue to promote educational activities and strengthen collaboration among medical institutions to help ensure that patients can make informed decisions based on their individual needs and preferences.

Furthermore, one of our key goals is to create an environment in which advanced surgical techniques and treatment options developed internationally can be widely and safely implemented in Japan. These include endoscopic and robot-assisted surgery, fat grafting, and prepectoral implant-based breast reconstruction. We aim to actively address the challenges associated with introducing and expanding access to these approaches in Japan, while carefully evaluating the safety and effectiveness of new technologies and medical devices.

By bringing together breast surgeons, plastic surgeons, and other healthcare professionals, we can further advance breast cancer care that achieves both oncological safety and aesthetic outcomes. Our society has an increasingly important role to play in making high-quality treatment available throughout Japan and bringing advances in breast surgery from around the world to patients in our country. With the continued support and cooperation of our members, I will devote my efforts to the further development of JOPBS.

I sincerely appreciate your continued support and cooperation.
