First of all, gastric Helicobacter pylori infection is one of the most important causative factors of gastric cancer. Gastric Helicobacter pylori is a bacterium that can live in the gastric mucosa. After infection, it can lead to the formation of chronic inflammation of the gastric mucosa. Long-term chronic inflammation will continue to irritate the gastric mucosa, leading to pathological changes in the gastric mucosa, thereby increasing the risk of gastric cancer.
Secondly, unhealthy lifestyle can also increase the risk of gastric cancer. Unreasonable dietary structure, high-salt, high-fat, and low-fiber eating habits are one of the main factors leading to gastric cancer. Long-term consumption of foods containing a large amount of salt and nitrite, such as pickles, bacon, etc., will increase the risk of gastric cancer. In addition, smoking and alcohol abuse are also important factors in inducing gastric cancer. Studies have shown that smokers and alcoholics have more than twice the risk of gastric cancer as non-smokers and non-drinkers.
Genetic factors also affect the occurrence of gastric cancer to a certain extent. If you have a direct relative with gastric cancer, your risk of developing gastric cancer will increase. Some genetic diseases, such as familial multiple polyposis and hereditary non-polyposis gastric cancer, can also increase the risk of gastric cancer.
The causes of gastric cancer are also related to age and gender. Research shows that the prevalence of gastric cancer increases with age, especially people over 50 years old are more likely to develop gastric cancer. In addition, the prevalence is significantly higher in men than in women, and the risk of gastric cancer in men is approximately twice that of women.
Other possible triggers include gastritis, gastric ulcers, persistent acid reflux, bile reflux, etc. These can cause inflammation and damage to the gastric mucosa and increase the risk of gastric cancer.
Taken together, the cause of gastric cancer is very complex and is caused by the combined action of multiple factors. Gastric Helicobacter pylori infection, unhealthy lifestyle, genetic factors, age and gender are all important factors affecting the incidence of gastric cancer. Therefore, we should pay attention to maintaining good living and eating habits, conduct regular health examinations, and detect and treat gastric diseases in time to reduce the risk of gastric cancer. At the same time, early diagnosis and treatment of gastric cancer are also very important, which can help improve the cure rate and survival rate of patients.
