Abstract: Smoking, a common behavior that causes health risks among adults around the world, is closely associated with the risks of developing various kinds of cancers. Nevertheless, the impact of smoking on preoperative risks and postoperative outcomes of cancer surgeries has been largely overlooked. Extensive basic medical and clinical research findings and prognosis data demonstrate that smoking is associated with increased risks of multiple perioperative complications, and that smoking affects the general prognosis of patients. Smoking cessation during the preoperative and perioperative periods effectively reduces these risks and improves the long-term postoperative outcomes of cancer patients. At present, health workers and patients are not giving adequate attention to smoking cessation interventions and the quality of interventions available is poor. Herein, we discussed the necessity of comprehensive and standardized smoking cessation services and made recommendations regarding the implementation of comprehensive and standardized smoking cessation services, providing support for cancer patients to access evidence-based care during the perioperative period.
