Associate Professor Kayoko Katayama has been involved in research related to national cancer control, with a focus on cancer epidemiology, for many years. Her current research theme is "Cancer Survivorship," she is a pioneer in this field as an epidemiologist in Japan. "Cancer Survivorship" refers to the process of living after experiencing cancer diagnosis and treatment, and it is an established concept in Europe and the United States. The environment in this field has undergone significant changes. Since January 2016, the "National Cancer Registry" has been launched based on the law, and statistics on all cancer incidences are being collected in all prefectures. The government has also started cancer education and awareness campaigns targeting the entire population. The key to research methodology is "collaboration with patients and the community." Associate Professor Katayama is actively involved in developing various educational programs on cancer in collaboration with medical professionals, including physicians and patients, and disseminating information.
