What should lung cancer patients eat?

　　Generally speaking, there is no specific saying of "what should lung cancer patients eat." Lung cancer patients can consume foods such as lily bulbs, almonds, pears, yam, and shiitake mushrooms. Additionally, under a doctor's guidance, they may use medications including gefitinib tablets, erlotinib hydrochloride tablets, icotinib hydrochloride tablets, morphine sulfate sustained-release tablets, and anlotinib hydrochloride capsules. The detailed information is as follows:

　　I. Foods

　　1. Lily Bulbs: Lily bulbs contain abundant proteins, starch, fats, calcium, and other nutrients. They have effects of moistening the lungs, relieving cough, clearing the mind, and calming the nerves, which can alleviate symptoms such as coughing and phlegm in lung cancer patients.

　　2. Almonds: Almonds have functions of relieving cough, alleviating asthma, moistening the intestines, and promoting bowel movements. If lung cancer patients experience symptoms like coughing and shortness of breath, moderate consumption of almonds may be beneficial. However, almonds should be properly processed to avoid poisoning.

　　3. Pears: Pears are rich in water, vitamin C, B vitamins, potassium, and other nutrients. They help moisten the lungs, clear heat, stimulate body fluid production, and relieve thirst. They are particularly effective in alleviating symptoms such as cough, dry throat, and thirst caused by lung dryness in lung cancer patients.

　　4. Yam: Yam is rich in amylase, polyphenol oxidase, and other substances that aid digestion and absorption in the gastrointestinal tract, thereby enhancing the patient's physical condition. Moreover, yam has functions of strengthening the spleen and nourishing the lungs, providing some benefit to the lung function of lung cancer patients.

　　5. Shiitake Mushrooms: Shiitake mushrooms contain lentinan and other components that can regulate the human immune system and enhance the patient's immunity. Shiitake mushrooms are also rich in proteins, B vitamins, iron, potassium, and other nutrients, providing essential nourishment for lung cancer patients.

　　II. Medications

　　1. Gefitinib Tablets: This medication is an epidermal growth factor receptor tyrosine kinase inhibitor. By inhibiting the epidermal growth factor receptor signaling pathway on the surface of tumor cells, it prevents tumor cell proliferation, metastasis, and angiogenesis. It is used for patients with locally advanced or metastatic non-small cell lung cancer who have sensitive mutations in the epidermal growth factor receptor gene.

　　2. Erlotinib Hydrochloride Tablets: This medication is an epidermal growth factor receptor tyrosine kinase inhibitor. Erlotinib specifically targets tumor cells, inhibiting the tyrosine kinase activity of the epidermal growth factor receptor, blocking the growth signal transduction of tumor cells, and inducing tumor cell apoptosis. It is mainly used for patients with locally advanced or metastatic non-small cell lung cancer who have failed at least one prior chemotherapy regimen.

　　3. Icotinib Hydrochloride Tablets: This medication is an epidermal growth factor receptor tyrosine kinase inhibitor. Its mechanism of action is similar to gefitinib and erlotinib. It can competitively bind to the tyrosine kinase active site of the epidermal growth factor receptor, thereby inhibiting tumor cell proliferation. It is suitable for first-line treatment of patients with locally advanced or metastatic non-small cell lung cancer who have sensitive mutations in the epidermal growth factor receptor gene.

　　4. Morphine Sulfate Sustained-Release Tablets: When tumors invade tissues such as the pleura or chest wall, or bone metastasis occurs, patients may experience severe pain. Morphine sulfate sustained-release tablets are potent analgesics belonging to the opioid class. They relieve pain by acting on opioid receptors in the central nervous system.

　　5. Anlotinib Hydrochloride Capsules: This medication is a multi-target tyrosine kinase inhibitor. It can inhibit kinase activities related to tumor angiogenesis, such as vascular endothelial growth factor receptor, platelet-derived growth factor receptor, and several other kinases. It also inhibits tumor cell proliferation. It is used for patients with locally advanced or metastatic non-small cell lung cancer who have progressed or relapsed after receiving at least two prior systemic chemotherapy regimens.

　　Lung cancer patients should maintain an optimistic mindset, eat a balanced diet, and avoid consuming spicy or irritating foods.
