As far as Chinese medicine is concerned, it is not recommended for patients with stomach cancer to eat mutton, which is easy to cause fire in the organism and is not easily digested and absorbed by the organism. If patients eat it, it may lead to indigestion and patients will experience clinical symptoms such as abdominal distension and nausea. After the occurrence of stomach cancer, patients need to have a light diet, mainly fluid and soft food, they can eat various kinds of porridge, cakes and rolls, fresh vegetables and fruits, and soy products, not meat. As far as modern medicine is concerned, meat is the main source of protein, so as long as it is cooked and boiled, chewed slowly, it can still be consumed properly. In addition to paying attention to diet, patients also need to improve their examination. If there is no contraindication to surgery, radical surgery for gastric cancer is the best treatment method. If surgery cannot be performed, chemotherapy, targeted therapy, immunotherapy, and traditional Chinese medicine can be applied to prolong the survival time of patients.
