Despite the rapid economic development in our country and the great improvement of people’s living standards, the incidence of cancer is increasing day by day, especially gastric cancer, which accounts for every It ranks first in the incidence of gastrointestinal tumors.
The incidence of gastric cancer also has obvious regional structural differences. The incidence is significantly higher than that in southern regions. And the incidence of male patients is higher than that of females, and it occurs most in middle-aged and elderly patients.
What are the causes of gastric cancer?
1, smoking
Smoke contains various carcinogens such as benzopyrene, polycyclic aromatic hydrocarbons, and dibenzocarbazole, which are one of the causes of esophageal cancer and gastric cancer. The harmful substances in tobacco will also enter the stomach with saliva and directly stimulate the gastric mucosa, causing submucosal vasoconstriction and spasm, and symptoms of ischemia and hypoxia in the gastric mucosa.
2. Alcoholism
Studies have shown that although alcohol itself is not a carcinogen, long-term consumption of strong alcohol with high alcohol concentration can not only change the internal environment of the stomach, but also stimulate the gastric mucosa of the digestive system , damage mucosal tissue, accelerate the absorption of carcinogens, and participate in the pathogenesis of gastric cancer. If you drink and smoke at the same time, the harm is even greater.
3. Supper
Many people go to bed after eating supper, and the interval between eating and sleeping is too short, which will increase the risk of gastroesophageal reflux, which will not only cause heartburn, but also damage The mucosa at the junction of the stomach and esophagus. Over time, “atypical hyperplasia” may develop, thereby increasing the risk of esophagogastric junction tumors.
4. Too hot food p>
The human digestive tract mucosa can only tolerate food at 50-60°C. If the temperature exceeds this temperature, the mucosa will be scalded. If you often eat hot food, the mucous membrane damage has not been repaired and you are scalded. Repeated scalding and repair will cause changes in the mucous membrane and further develop into cancer.
Stomach cancer is not “painless”? Doctor: If these 4 abnormalities appear in the body, please be vigilant
Stomach cancer can be completely asymptomatic in the early stage, but it also has some common uncomfortable feelings. It can be said that the symptoms of the digestive tract are not very specific. For example, stomach diseases and intestinal diseases may all have similar discomfort.
1. Epigastric discomfort p>
The most common initial symptom in gastric cancer, present in about 80% of patients, is similar to dyspepsia. If abdominal pain occurs, it usually begins slightly and is irregular. It cannot be relieved after eating and gradually increases, which can be dull or dull pain.
Some may have rhythmic pain, especially gastric antrum and gastric cancer, which can be relieved by eating or taking medicine. The elderly suffer from sluggish pain, and mostly complain of abdominal distension.
2. Loss of appetite and weight loss
< p data-track="18"> Loss of appetite and weight loss are the second most common symptoms of gastric cancer. Nearly 50% of gastric cancer patients have obvious symptoms of loss of appetite or inappetence. Some patients restrict their food intake on their own due to overeating, which may cause abdominal distension or abdominal pain.
Unexplained anorexia and weight loss are likely to be the initial symptoms of early gastric cancer and need attention. Patients with early gastric cancer generally have no obvious positive signs, and most patients only have deep tenderness in the upper abdomen except for the weak general condition.
3, loss of appetite, indigestion
Many people often experience poor appetite for no reason, even the food they like, such as meat and greasy food Especially disgusting, even changing the recipe did not improve significantly. Even if there is a slight improvement, loss of appetite will appear again in the short term, and in many cases, it will be accompanied by acid reflux, heating, etc.
About 68% of gastric cancer patients will have these symptoms, and because they are similar to gastritis and ulcer disease, and are often ignored.
4. Dark or bleeding stools
Bleeding black or dark stools is normal when eating pork liver, sweet potatoes, dragon fruit, blood tofu, or iron supplements.
But if these conditions are excluded, black stools will occur, or even bloody stools will be discharged directly. The possibility of gastric cancer should be considered. Gastric cancer patients often have a small amount of bleeding in the stomach and intestines. If they are not paid attention to, they will aggravate the disease.
How to prevent stomach cancer?
Stomach cancer is caused by “eating”, so the prevention of gastric cancer should also start with “eating”. In the past five years, the incidence of gastric cancer among 19-35 year olds has been quite high, which is caused by irregular diet, so how should gastric cancer be prevented? Here are some foods that you eat regularly that can effectively prevent or reduce the occurrence of cancer.
1, onion
Eating onions can reduce the content of nitrite in the stomach. It is important that onions contain a substance called quercetin, which is a natural anti-cancer substance. Studies have shown that people who regularly eat onions are 25% less likely to develop stomach cancer and 30% less likely to die from stomach cancer than those who eat less or no onions.
2, cauliflower
Cauliflower contains more trace elements molybdenum, which can block the synthesis of carcinogenic amine nitrite, and can play an anti-cancer and anti-cancer effect. Some studies have pointed out that cauliflower also contains an enzyme that can stimulate cell activity called small sulfide, which can prevent the formation of cancer cells. Eating cauliflower has a certain effect on preventing esophageal cancer and stomach cancer.
3. Green tea
Green tea is one of the natural anti-cancer agents that has recently gained a lot of attention. Human experiments have confirmed that drinking 1 to 5 grams of tea made from tea leaves can significantly block the synthesis of nitrite in the body. Beijing Medical University reported that green tea contains various nitrosation inhibitors such as vitamin C, vitamin E and tea polyphenols.
4, Eggplant
Eggplant is rich in vitamin P, and nightshade vegetables contain important phytochemicals, which have been shown to prevent the formation of cancer cells. Eggplant has three anti-cancer effects: dispersing blood, relieving pain, reducing swelling, and widening the intestines. Some patients with gastrointestinal cancer undergoing chemotherapy, appear When the elbow is hot, eggplant can also be used as an adjuvant therapeutic food.
80% of early gastric cancers can be prevented and treated. It’s not scary, it’s really scary if it’s discovered too late. In addition to identifying the 4 major signs before the advent of gastric cancer, adequate preventive work should also be done.
Helicobacter pylori is the No. 1 carcinogen that causes gastric cancer. If someone in the family carries this bacteria, almost everyone will be infected. Therefore, for the health of yourself and your family, you must prevent For Helicobacter pylori infection, start with a pair of public chopsticks and appropriately change the way of eating, so as to reduce the risk of gastric cancer.
