The four major goals of cancer rehabilitation: ① psychological support at the time of diagnosis, ② maintaining optimal physiological function after treatment, ③ vocational counseling when needed, and ④ ultimately achieving the optimal social function for cancer treatment and control. Rehabilitation of cancer patients is not only a matter of oncology, but also involves many disciplines such as psychology, nutrition, sociology and so on. Cancer prevention and treatment is actually “group prevention and treatment”. Therefore, it is a social system project. Cancer is an important disease of the elderly. Its treatment requires the close cooperation of professionals from various disciplines, such as surgery, radiotherapy, chemotherapy and traditional Chinese medicine, in order to obtain the best therapeutic environment.
