Hello, I'm a doctor from Zibo Wanjie Cancer Hospital. For what you said, I suggest your family strengthen nutrition, improve immunity and fight cancer. At present, only good health can eliminate or fight cancer cells. Dietotherapy after lung cancer surgery should be the first important, because neither Chinese nor western medicine can cure lung cancer radically. Anti-tumor foods such as sea cucumber, asparagus, healthy porridge, five elements vegetable soup, sweet potato, cauliflower, Chinese cabbage, mushrooms, fungus and so on. Sea cucumber: You should eat it every day, with water, sea cucumber, or sea cucumber capsules. Water-soaked sea cucumber should be eaten on an empty stomach, with soy sauce or honey, not less than 50g at a time. Asparagus: No less than 50g three times a day, not eaten raw. It is best to eat asparagus. Canned asparagus maintains a high nutritional value. Fresh asparagus is poor. Asparagus is not only a kind of food with high nutritional value, but also a world-recognized anti-tumor food and a medicinal material. It has special effects on lung cancer. Five elements vegetable soup is also good for conditioning the body. Ten grains of healthy porridge: much better than eating a single staple food. Patients generally don't eat much. Other anti-tumor foods can be eaten often. Food is not medicine, it will be effective if they insist on eating it.
