It is necessary to structure a research and treatment system for squarely dealing with an elderly patient's cancer in Japan as a country with arrival of a super aging society. For that reason, it is important for healthcare professionals who provide medical care and rehabilitation to comprehend physical/mental characteristics of elderly patients. Cancer rehabilitation has been implemented so far, but there is still no clear relation between "Cancer" and "Rehabilitation" yet. Firstly, it calls for urgent attention to actually practice a cancer rehabilitation by accurately assessing a cognitive function and physical function of elderly patients. Furthermore, it is preferable that assessment results/issues in clinical practice should be utilized not only for healthcare professionals but also for development of welfare equipments. Even though it might be difficult to be directly connected between patient and engineer, it could make a contribution to a development of Kansei engineering in future through healthcare professionals such as occupational therapist.
