“Doctor, please help me, I have stomach cancer!” An uncle who looked to be in his early 50s pushed the doctor’s consultation room with his stomach covered, and said he had stomach cancer as soon as he opened his mouth.
This person’s surname is Wang. Uncle Wang has no idea what’s going on recently. He has inexplicable abdominal distension and often farts. He searched the Internet and did not expect that a topic on stomach cancer popped up on the webpage. The article inside told him It may be stomach cancer, and let him go to the hospital for examination.
Seeing the word stomach cancer, Uncle Wang’s three souls were immediately scared out of his mind, he hurriedly took a taxi and came to the hospital, which is where the scene at the beginning happened.
“Don’t worry, do a gastroscopy.” The doctor comforted calmly, because Uncle Wang didn’t eat anything in the morning, so he just gave it on an empty stomach. He arranged for a gastroscopy. The results showed that the mucosa was smooth and everything was normal.
Uncle Wang finally felt relieved when he saw the results of the colonoscopy, but he also wondered, if he didn’t have stomach cancer, why would he still be bloated and fart a lot?
I. Abdominal distension and excessive farting, is it a sign of stomach cancer?
I feel that my stomach is swollen before I eat two mouthfuls of rice, and I often feel that there is gas in my stomach “running around”, and I always fart… I believe many people have had this experience. These phenomena are generally related to the following reasons:
1. Poor diet
Eating too much potatoes, flour, sugar and other gas-producing foods , It is easy to create gas in the stomach and cause abdominal distension; there are also some indigestible foods, such as vermicelli, fried beans, hard pancakes, etc., due to indigestion, stay in the stomach for a long time, and also easily cause abdominal distension.
2. Eating too fast
The habit of gobbling down, or eating while walking is easy to swallow. With little air, a lot of air is stored in the intestines, and the abdomen can easily cause bloating.
3. Emotional anxiety
Anxiety, anxiety, sadness, depression and other negative emotions may also weaken the digestive function and stimulate the stomach to secrete too much gastric acid. Causes increased bloating.
4. Digestive system diseases
Gastrointestinal diseases such as chronic gastritis, gastric ulcer, intestinal tuberculosis, intestinal obstruction, etc., will also show Abdominal bloating and other issues.
5. Others
In addition, acute peritonitis, angina pectoris, arrhythmia, postoperative intestinal paralysis, spinal lesions, chronic pelvic inflammatory disease, etc., may also cause bloating performance.
Second, tell you the real symptoms of gastric cancer!
Abdominal pain is not necessarily caused by gastric cancer. The symptoms of early gastric cancer are not typical and may be accompanied by the following symptoms:
1. Distending pain
mainly manifested as dull and dull pain in the upper abdomen. The pain was mild at the beginning and gradually increased at the end. This manifestation is often mistaken for gastritis, and the symptoms will be temporarily relieved after treatment, but the pain degree will continue to increase in most patients.
2. Nausea and acid reflux
When the lesion of gastric cancer is located in the pylorus, the most obvious early symptom is often nausea. Once the gastric outlet is completely blocked, a sour or rotten egg smell will be produced.
3. Hematemesis and melena
If the tumor invades and destroys the small blood vessels in the stomach, the main symptoms are: Occult blood in the stool – the stool is normal in appearance, but blood cells can be seen in it after a test. Hematemesis or tarry black stools occur if the tumor invades and destroys large blood vessels.
4. Fatigue and weight loss
Patients will lose weight suddenly in a short period of time. This is due to the constant preemption of nutrients by normal cells during tumor growth. And tumor growth also consumes energy, causing patients to lose weight and energy.
Third, Test: if the score exceeds 12, hurry up and go to endoscopy
my country is a country with a high incidence of gastric cancer , 670,000 new cases of gastric cancer occur every year. At present, there is a lack of effective tumor molecular markers for gastric cancer detection. To screen cancer at an early stage, gastroscope is the best method.
Gastroscope (endoscope) is a tube with a length of about 1~1.5 meters and a diameter of about one centimeter. The front end integrates a high-definition camera and a light bulb. The tube can penetrate deep into the wall of the digestive tract to observe whether the surface structure of the wall and blood vessels are abnormal, so as to detect the lesions early and make a biopsy for diagnosis.
Academician Li Zhaoshen’s team from the National Clinical Research Center for Digestive Diseases has developed the Li’s Scale for more than two years to test the risk of gastric cancer.
Different score suggestions:
1. High-risk population of gastric cancer (17-23 points): The risk of gastric cancer is extremely high, and endoscopy is strongly recommended, and endoscopy is performed every year.
2. People with intermediate risk of gastric cancer (12-16 points): There is a certain risk of gastric cancer, so gastroscopic examination is recommended, and gastroscopic examination is performed every two years.
3. Low-risk population of gastric cancer (0-11 points): The risk of gastric cancer is average, and regular follow-up can be performed, and gastroscopy is performed every three years.
Fourth, half of the world’s gastric cancer is in China, and there are 4 points to prevent gastric cancer
According to the 2020 global cancer burden released by the World Health Organization’s International Agency for Research on Cancer Data show that in 2020, there were 1.089 million new cases of gastric cancer worldwide, of which 478,000 (43.9%) were new cases of gastric cancer in China. From the data, China is the country with the largest incidence of gastric cancer.
Based on this background, Academician Shen Hongbing of Nanjing Medical University, Prof. Jin Guangfu, Prof. Li Liming of Peking University, Prof. Lu Jun, and Fudan University Wei Qingyi Professor Yang Ming from the Cancer Hospital of Shandong First Medical University, etc. conducted the largest genome-wide association analysis (GWAS) study of gastric cancer in the Chinese population to date.
Research shows that genetic risk and lifestyle are the two major reasons for the high incidence of gastric cancer in Chinese. More importantly, developing 4 good habits – no smoking, no drinking, less pickled food, and more fresh fruits and vegetables can effectively reduce the risk of stomach cancer by 47%. Even for people with high genetic risk of gastric cancer, adhering to a healthy lifestyle can reduce the 10-year absolute risk of gastric cancer by 1.12%.
To prevent the occurrence of gastric cancer, it is inseparable from the improvement of daily life and regular gastroscopy. Stomach cancer is not scary, what is scary is that when it happens, you are still in an unknown state and let it develop.
