Abstract: Breast cancer is considered as a chronic disease, hence breast cancer these patients require extensive and effective chronic disease management. With the development of the "Healthy China 2030" program and the "Comprehensive Management Guideline for Breast Cancer Follow-up and Concomitant Diseases, "more attention is being paid to the management of concomitant diseases of breast cancer (CDBC). This involves improving multidisciplinary treatment by collaborating with oncologists and related specialists to develop psycho-oncology, oncocardiology, and other oncology subdisciplines. Consultation-liaison psychiatry has been successfully used in the treatment of patients with cancer. Therefore, for the prevention and treatment of CDBC, it is important to establish and improve rehabilitation medicine and other units, such as cardiovascular, endocrinology, and gynecology units. This, in turn, could help improve the patient's quality of life and prognosis.
