Try to eat as little chili pepper as possible in the advanced stage of lung cancer, but if the patient specially requests, he/she can consume chili pepper in moderation. Chili belongs to irritating food, which has certain damage to oral cavity, esophagus and gastric mucosa, and consuming a large amount of chili itself is not a good life habit. Lung cancer at advanced stage is a clinically incurable malignant tumor, and the main purpose of treatment is to relieve pain, improve clinical symptoms, and improve the quality of life. If patients have a strong will to consume chili peppers, they can consume chili peppers in moderation to satisfy their needs of taste and spirit. Therefore, although consuming a large amount of chili peppers is a bad dietary habit, advanced lung cancer patients with strong will can eat in moderation.
