Radiation Oncology

About us

Radiation oncology is a field of treating cancer using radiation, and has a 120-year history since attempts to use radiation to cure diseases began a year after Dr. Röntgen's discovery of radiation in 1895.
Cancer is the leading cause of death among Japanese people and the number of patients will still increase with advancement of aging society. Radiotherapy is characterized by its low invasiveness, low patient burden, good functional preservation, ability to treat lesions that are difficult to treat with surgery, and high quality of life (QOL) after treatment. Therefore, the role of radiation therapy will increase as the super-aging society progresses.
New technologies, such as intensity-modulated radiation therapy (IMRT), stereotactic radiotherapy (STI), image-guided radiotherapy (IGRT), and particle therapy (e.g. proton therapy and carbon-ion therapy) are now widely used and have been enabled highly precise irradiation to the tumor with less irradiation to normal tissues. Technological advances in these high-precision radiotherapy are still in the developing stage, and further progress is highly anticipated.
Providing the best medical care is the founding spirit of our university. Our department has more than 70 years history of radiation oncology research, Professor Tasaki, our second chief professor, was the first president of Japanese Society of Radiation Oncology (JASTRO), and the first annual meeting of JASTRO was held at Yayoi Memorial Hall of our university in 1989, large number of clinical data has been accumulated for clinical study.
The aim of our department is to develop outstanding researchers, clinicians and educators. Our department has experts in clinical radiation oncology, medical physics, and radiation biology and also has a strong joint research system with researchers of National Institutes for Quantum Science and Technology (QST).
We accept a wide range of graduate students not only physicians but also those with backgrounds in science, engineering, and radiological technology to conduct a wide range of clinical research and R&D.
