Self-introduction
I specialize in cancer chemotherapy and supportive care. Although my research area is mainly on lung cancer, I am responsible for the treatment of a variety of cancers in my practice, including orphan cancers, cancers of the young generation, and difficult-to-diagnose cases. I also serve as the Deputy Director of the Division of International Medical Support.
