Associate Professor Takehiko Yokobori is working on two challenging themes related to cancer. One is the development of ideal antibodies that attack cancer cells and enhance immune function. The other is the creation of "cancer markers" that can detect the presence and progression of various types of cancer. He is a surgeon, and he started researching "cancer markers" during the latter stages of his graduate program, but after completing his studies, he transitioned to the clinical field. After that, however, he shifted his focus towards research. He felt a growing desire that if patients' diseases could be diagnosed earlier, he could help more cancer patients. Therefore, he is actively engaged in research to deliver his findings to patients suffering from cancer and make a difference in their lives.
