Ranking of gastric cancer triggers! 6 high-risk factors you must pay attention to!


Nowadays, “ten stomach diseases and nine stomach diseases” have become the norm. Many people will experience gastric discomfort such as stomach pain, bloating , and acid reflux in life, but this may be the “last cry for help” issued by the stomach. As a country with a high incidence of gastric cancer , China accounts for about half of the world’s new cases and deaths. Gastric cancer is one of the most common malignant tumors . Almost 3 people die from gastric cancer every 5 minutes in China. Therefore, prevention and early detection of gastric cancer are crucial to understand the risk factors of gastric cancer and stay away from it as much as possible. The following six high-risk factors may induce gastric cancer! Hope you don’t have any!

1. Sixth: Long-term drinking

Research shows that the impact of alcohol on gastric cancer is generally declining, but it is still a major predisposing factor. It is expected that 2.09% of gastric cancer cases will be attributed to alcohol in 2050. Alcohol can seriously irritate the gastrointestinal tract, causing nausea, vomiting, abdominal pain and other reactions, causing gastric mucosal damage and bleeding, and increasing the risk of gastric cancer. Therefore, for wine , it is recommended not to drink alcohol. You can quit smoking early and avoid risks in time.


2. Fifth place: Pickled foods

in pickled foods Nitrosamines and nitrites may cause cancer, and long-term intake will increase the risk of gastric cancer. According to the “Public Guidelines for Gastric Cancer Risk Management for the Chinese People” (2023 Edition), the risk of gastric cancer when eating pickled foods regularly is 2.21 times higher than eating less of these foods.

Suggestion: Eat as little pickled food as possible. If you must eat it, you can also eat some foods rich in vitamin C, such as kiwi, cherries, strawberries, and oranges. This is because vitamin C can effectively prevent the formation of nitrosamines and try to prevent the body from absorbing carcinogens.

3. Fourth place: diabetes

Diabetes is a factor that is rising sharply, with cases expected to be attributed to diabetes in 2050 compared to just 0.44% in 2020. This is mainly related to the increasing incidence of diabetes year by year. Patients with type 2 diabetes are susceptible to gastric cancer because insulin resistance and hyperglycemia increase the risk; at the same time, hyperglycemia and glucose metabolism disorders may damage the immune system and make patients more susceptible to Helicobacter pylori infection; in addition, there is a link between diabetes and gastric cancer. Common risk factors such as obesity and unhealthy diet.


Recommendation: The daily intake of added sugar for adults should not exceed 50 grams, preferably less than 25 grams, and drink less sugary drinks and more boiled water every day. Diabetic patients should actively follow the doctor’s advice, control their diet, and stabilize blood sugar levels.

4. Third: Obesity

In recent years, the overweight and obesity rates in our country have been increasing, and obesity is generally considered to be an inflammatory and carcinogenic state. Research shows that people with larger waistlines have a 38% higher risk of stomach cancer than those with smaller waistlines. It is expected that 11.89% of new cases in 2050 will be attributed to obesity, nearly double the 6.68% in 2020.

Recommendation: Overweight people should stay away from overeating, high-fat diet, high-protein diet, and high-calorie diet. They should have a regular daily life, balance work and rest, and eat less and move more.


5. Second place: Smoking

When it comes to smoking, many people may first think of lung cancer, but surprisingly, smoking is actually the second major cause of gastric cancer. The harmful substances in tobacco irritate the gastric mucosa, cause abnormal cell proliferation, and increase the risk of gastric cancer. Smokers had a 61% increased risk compared with never smokers, and smokers had a 43% increased risk.

It should be noted that even if you do not smoke, you should avoid entering second-hand smoke environment, as it will increase the risk of cancer.

6. First place: Helicobacter pylori infection

Helicobacter pylori is currently the only bacterium that can survive in the human stomach and is mainly spread through the digestive tract. According to the 2023 edition of the “White Paper on the Prevention and Treatment of Helicobacter pylori Infection in China”, the Helicobacter pylori infection rate in China is nearly 50%, and 70% of gastric cancers are related to Helicobacter pylori.


In the early stages of an infection, patients may have no obvious symptoms, but that doesn’t mean their condition isn’t serious or doesn’t require treatment. They may have a chronic progressive development. Among them, 5% to 10% have indigestion, 15% to 20% have peptic ulcers, and 1% eventually develop gastric malignant tumors.

Here’s a reminder: If you have irregular stomach pain, repeated stomach pain, rapid weight loss, heart mass, black unexplained bowel movements and other symptoms, it may be a sign of gastric cancer and you need to be highly vigilant.
