Stomach cancer refers to malignant tumours occurring in the stomach, which generally originate from epipelagic cells and are the most common malignant tumours in digestive tracts. In recent years, with changes in dietary structure and habits, exposure to high-risk factors has increased and the age at which stomach cancer occurs has rejuvenated. From a nutritional perspective, attention and prevention of stomach cancer will be given to the following.
1. Catastrophe of stomach cancer is a multi-factor, multi-step and multi-stage process, and it is generally believed that it is caused by a combination of: 1. Poor living and eating habits, such as high levels of smoking, alcohol consumption, strong tea, strong coffee, barbecue, fried, fast foods, high sugar, salt and fat diets, as well as a preference for pickled foods. Sphinx infection: one of the main causes of stomach cancer. 3. Genetic factors: In the case of a family with stomach cancer, the incidence of stomach cancer is higher than in the general population. 4. Degenerative diseases: Chronic atrophy of stomachitis, stomach stomach flesh, stomach ulcer etc. 5. Geographical environmental factors: There are significant geographical differences in the incidence of stomach cancer, which may be related to local eating habits, environmental pollution, etc. For example, stomach cancer is significantly higher in the north-west and east coasts than in the south.
II. Clinical performance of stomach cancer
The majority of early stomach cancer patients have no visible symptoms, and a few have symptoms such as nausea, vomiting and abdominal discomfort, with some showing symptoms of stomach ulcer without specificity. As a result, early detection of stomach cancer is low.
Stomach cancers during the period of progress are: 1. abdominal pain: a very small number of patients who have a carcinogenic ulcer perforation can also experience abdominal pain and peritoneal irritation. 2. Declining appetites and wasting: Patients can suffer from a decline in appetite, aggravated wasting, inactivity, anaemia, malnutrition, etc., which can lastly be characterized by malign conditions. Disgusting: It is one of the more common symptoms of stomach cancer that can occur at an early stage. Stomach cancer can cause gypsies, which can lead to nausea and vomiting. 4. The difficulty of the oesophagus: gland cancer in the oesophagus combined can prevent the passage of food and give rise to difficulty and a sense of resistance. 5. Indigent haemorrhage: Patients with stomach cancer often lose a small amount of blood, in the form of faeces positive or intermittent black defecation, with vomiting in the case of serious cases.
Diagnosis of stomach cancer 1. Endoscopy: The diagnosis of cancer cells is based mainly on a gastroscope examination and pathological biopsy; 2. Blood and constipation: an anemia can be detected in blood analysis and periphery positive can be detected; 3. Oncology markers: cancer embryo antigens, CA199, CA125, etc. help in the diagnosis of stomach cancer; 4.CT: A CT can diagnose stomach cancer in stages, helping to determine the extent of the disease and whether it is transmitted.
Nutritional guidance for stomach cancer prevention
Nutritional guidance to prevent stomach cancer is an important measure to maintain stomach health and reduce the risk of stomach cancer. The following are specific nutrition recommendations: 1.

(3) High-quality proteins, such as chicken, fish, shrimp, beans, etc., with high-quality proteins and essential amino acids, contribute to the maintenance of normal body metabolism and immune functions. (4) Selenium: Selenium is an antioxidating trace element capable of inhibiting the growth and spread of cancer cells; beryllium-rich foods include silver ears, mushrooms, garlic, etc. 2. Avoid harmful food intake (1) High salt foods: such as salted fish, pickles, ham intestines, etc., high salt diet not only causes health problems such as hypertension, but may also increase the risk of stomach cancer.
