I. Basic knowledge of gastric cancer
A large number of epidemiological investigation data show that the development of gastric cancer may be the result of the interaction between environmental factors and intrinsic factors of the body.
1.Dietary factors: some foods contain direct carcinogens, smoke and frying can produce polycyclic aromatic light compounds, which can contribute to the occurrence of gastric cancer. Moldy foods such as peanuts and corn contain aflatoxin, which can induce gastric cancer. High-salt diets such as cured fish and salt dishes are also noted. Some foods contain indirect carcinogens, which can be transformed into carcinogens and lead to the occurrence of gastric cancer when the human body has low or lack of stomach acid and many clusters of bacteria are present in the stomach to reproduce.
2.H. pylori: The risk of gastric cancer is 6 times higher for those infected with H. pylori than those without infection.
Genetic factors: Although genetics is not an important factor for the occurrence of gastric cancer, it is aggregated in a few families.
4.Other diseases in stomach: chronic gastric constrictive gastritis, chronic gastric ulcer, adenoma and polyps are related to the occurrence of gastric cancer.
Prevention of gastric cancer
Eating less salt-cured food.
Avoid eating rough food.
Eating more fresh vegetables and fruits and drinking more milk.
Eating less salt-smoked, fried and baked foods.
Eating on time and avoiding overeating.
Food should not be too hot and should not be eaten too quickly.
Eating in a happy and cheerful mood.
Do not drink strong alcohol and smoke less or not smoke.
Common symptoms of stomach cancer
1. Upper abdominal pain: it is the most common symptom and also the most unspecific and neglected symptom.
2.Loss of appetite, emaciation, weakness, nausea and vomiting.
3, bleeding and black stool: only positive fecal occult blood in small amount of bleeding, when the bleeding is larger there can be vomiting blood and black stool.
4.Other symptoms: some may have diarrhea, fever, etc.
Treatment and post-operative rehabilitation of gastric cancer
Gastric cancer is mainly treated by surgery, and other treatments include chemotherapy, radiotherapy, immunotherapy and Chinese herbal medicine treatment. The 5-year survival rate of early gastric cancer after surgery is 95%-98%, while that of progressive gastric cancer is only 20%-30%. Therefore, early detection, early diagnosis and early treatment are the most effective measures to improve the prognosis of gastric cancer.
Regular re-examination should be insisted after surgery in order to detect problems and deal with them in time.
In the first year after surgery, the review should be conducted every 2-3 months.
In the second to third year, it should be reviewed once every 3-6 months.
After 3 years, it will be reviewed once every 6 months.
After 5 years, it should be reviewed 1-2 times a year.
V. Common tests for gastric cancer
1.Laboratory examination: blood routine, fecal occult blood test, liver and kidney function.
2.X-ray barium meal examination
3.Gastroscopy
4.B-ultrasound examination
5.CT examination
6.Biochemical and immunological examination: CEA, etc.
Early symptoms of gastric cancer
Upper abdominal discomfort, pain, poor appetite, acid reflux and belching are the early symptoms of gastric cancer.
Further examination should be conducted for those who have the following conditions.
1. Over 40 years old with gastrointestinal symptoms lasting for 3-6 months.
2.History of “gastric disease” which has been aggravated recently.
3.Proven chronic gastritis, chronic gastric ulcer, gastric polyp.
4.Persons with long-term positive fecal occult blood test.
