Abstract： This article is to introduce the clinical experience of Professor HOU Shufang in staging treatment of lung cancer. Professor HOU Shufang holds that the deficiency of healthy qi is the root of lung cancer， and heat， phlegm， stasis， and toxin are branches of lung cancer. Professor HOU accurately grasps the entry point of integrated Chinese and western medicine in the treatment of lung cancer， proposing the viewpoint of staging treatment of lung cancer，dividing the prevention and treatment process of lung cancer into stages such as observation of lung nodules， postoperative recovery or follow-up of patients，radiotherapy，targeted therapy，chemotherapy，and end-stage treatment，fully leveraging the auxiliary and leading role of Chinese medicine.
