In daily life, people are often afraid of cancer. Cancer refers to malignant tumors that originate from epithelial tissues and is the most common type of malignant tumors. Today we are going to learn about gastric cancer .
Gastric cancer refers to a malignant tumor that occurs in the gastric mucosal epithelium. At present, gastric cancer is one of the most common malignant tumors worldwide, and its incidence is second only to lung cancer.
Early symptoms of gastric cancer are often not obvious, and symptoms such as upper abdominal discomfort, dull pain, belching , pantothenic acid , loss of appetite, mild anemia, etc., which are not easy to attract people's attention. Therefore, when there is abnormality in the body, you should go to the hospital for examination in time.
What are the factors that cause gastric cancer?
. Helicobacter pylori infection
Helicobacter pylori infection will lead to the emergence of gastric cancer. Through research, helicobacter pylori will induce chronic active gastritis after entering the human body. As the disease continues to develop, the patient's digestive tract will have ulcers, and the gastric mucosa will be damaged, which will make the condition more serious.
. Environmental factors
For people living or working in a chemically contaminated environment for a long time, for example, water and soil contain too much nitrate , volcanic rock areas, etc., which can easily cause cell carcinoma, thereby leading to gastric cancer.
. Dietary reasons
If you regularly eat some smoked or barbecued foods, it will increase people's risk of gastric cancer. This is because these foods contain some carcinogens. Eating these foods for a long time will cause these carcinogens to accumulate in the body and easily induce cancer.
. Genetic factors
In the incidence of gastric cancer, there is a relatively obvious family aggregation phenomenon. People with a family history of gastric cancer have a significantly higher incidence rate than those without a family history of gastric cancer, indicating that there are certain genetic factors in the cause of gastric cancer.
. Stomach disease
Stomach disease is an organic or functional disease of the stomach. Common clinical cases include chronic gastritis, peptic ulcers, and gastric cancer. The main symptoms include upper abdominal pain, burning nausea, vomiting, belching, acid reflux, loss of appetite, vomiting of blood, blood stool , lumps, etc. If you do not pay attention to it, you will easily develop into gastric cancer.
. People with low immunity
Home immune function has a higher incidence of gastric cancer, which may cause immune dysfunction in the body and reduce the immune supervision effect on cancer.
. Smoking and drinking
The main reason for smoking and drinking is that nicotine and alcohol in cigarettes can enter the stomach through the digestive tract, stimulating our gastric mucosa. Over time, it will cause bleeding and edema, and even gastric ulcer . If the gastric ulcer develops in another step, it may be gastric cancer.
The appearance of gastric cancer does not itch or pain?
The early stage of gastric cancer usually does not have obvious clinical symptoms, and it is difficult to cause the patient to notice it because it is not painful or itchy. This is because early gastric cancer is usually limited to the mucosal layer or submucosal layer. The damage caused locally does not send obvious signals to the body, especially when the lesion range is relatively small.
Some people may experience symptoms such as dull abdominal pain, bloating, nausea, vomiting, belching, and impotence of stools. If there is no obvious effect after drug treatment, sufficient attention should be taken.
If there are 6 abnormalities after eating, or check it in time
. The stool is black
The color of normal and healthy people is related to what we eat that day or the day before yesterday, but if you do not eat black foods, but your stool suddenly appears black, it is very likely that there is a stomach problem. You should pay attention to it and take the test in time.
. Weight loss
When there is abnormality in the stomach, the body's digestive and absorption capacity will be affected, which can easily lead to decreased appetite, diarrhea, etc. If you control your body shape in a short time, but your weight drops significantly, you should pay attention to it. Not only can the body be unable to absorb nutrients from food, cancer cells will also compete with the body for the remaining nutrients.
. Heartburn acid reflux
Heartburn acid reflux refers to the burning sensation that occurs near the lower part of the sternum, which is commonly known as the "heart". When the heartburn acid reflux phenomenon occurs repeatedly, it is likely to be a gastric acid secretion disorder caused by the tumor, and needs attention.
. Stomach pain
Problems in the stomach will cause stomach pain, and the same is true for stomach cancer. When you feel stomach pain is a pain that cannot be stopped for a long time, it means that there is a problem with your stomach, which is most likely stomach cancer.
When we press, the pain will radiate to the back and even the navel. At this time, we must pay attention and go to the hospital for examination in time.
. A feeling of fullness
When there is a problem with the stomach, you will feel uncomfortable in the upper abdomen. This is the most common early symptom of stomach disease or gastric cancer. Especially after eating, even if you eat very little, you will have abdominal distension. After a period of time, this feeling of fullness will slowly disappear. This may be an early symptom of gastric cancer. You must go to the hospital for gastroscopy in time.
. Hiccups frequently
If you eat too much, or have indigestion, you will experience hiccups, but the hiccups will not last long and will return to normal after a period of time. In the early stage of gastric cancer, the continuous growth of cancer cells will affect the breaking of the diaphragm and disrupt the nervous system that controls the diaphragm, which will lead to frequent hiccups.
How to prevent the occurrence of gastric cancer in daily life?
. Quit smoking and quit drinking
Many people have the habit of smoking and drinking. Smoking and drinking have a great impact on the body, especially the damage to the gastric mucosa. Long-term smoking and drinking will lead to increased permeability of the cell membrane and promote the absorption of carcinogens. Therefore, we must try to quit smoking and quit drinking.
. Reasonable diet
Don’t eat too much salty and spicy food, and don’t eat too hot, too cold, expired or spoiled foods; elderly, weak or have some disease genetic gene , eat some cancer-proof foods and alkaline foods with high alkali content as appropriate, and maintain a good mental state.
Eat different types of fresh fruits and vegetables every day, Plant food is rich in fiber, antioxidants and anti-cancer substances, which can effectively prevent cancer. A reasonable diet is the source of health.
. Persist in exercise
Gastric cancer This disease can also be prevented by exercise. Exercise can inhale several times to dozens of times more oxygen than usual. Medical research shows that the body's oxygen inhalation increases and the respiration rate increases. Through gas exchange, some carcinogens can be excreted out of the body, reducing the incidence of cancer.
insist on aerobic exercise, which can indeed prevent the occurrence of cancer to a certain extent. In daily life, you can exercise by swimming, jogging, brisk walking , playing ball, playing Tai Chi , dancing square dance and other exercises.
. Regular physical examination
If there are high-risk factors for gastric cancer, such as having atypical gastric hyperplasia and intestinal metaplasia of the stomach, or Helicobacter pylori infection , it is recommended to have a gastroscopy once a year, and those with a family genetic history should also pay attention to regular physical examinations. People with no abnormal stomach problems are recommended for gastroscopy 2-3 years. Once atypical dysplasia in the stomach or intestinal metaplasia and other precancerous lesions of , should be actively treated.
