This paper describes the mechanisms, implementation steps, clinical application effects, and assessment tools commonly used in the implementation of behavioral speech therapy applied in patients with chronic cough after lung cancer surgery. Behavioral speech therapy consists of four steps: education, laryngeal care and hydration strategies, cough suppression techniques and psychological counselling. Behavioral speech therapy can reduce the frequency of coughing, improve the life quality, and save medical costs. It is proposed that nurses′ roles in behavioral speech therapy should be further played and the technique should be applied to preoperative and community care.
