Is stomach cancer contagious? Normally it is not contagious, but prevention is still necessary

Gastric cancer is caused by bad living habits or Helicobacter pylori infection, as well as genetic factors or bad environment. This disease is not contagious. As long as gastric cancer is discovered in the early stages and treated in time, it generally will not have much impact on the patient. However, if gastric cancer is too serious, it will affect life.

Gastric cancer is a very worrying disease. This disease has a great impact on the patient. Many patients do not even know how gastric cancer came about, so they suspect that they have come into contact with some gastric cancer patients and have been infected. So is gastric cancer contagious? The following are some explanations for this question.
Not only gastric cancer, but also other malignant tumors are the same. It is not an infectious disease and cannot be transmitted from one person to another. Gastric cancer is caused by Helicobacter pylori infection, which is an important factor causing gastric cancer. Therefore, the eradication of Helicobacter pylori is very important.
If someone in the family is infected with Helicobacter pylori, it may be transmitted to other family members, so this is just about Helicobacter pylori infection. But it does not mean that it will cause stomach cancer, because stomach cancer itself is not contagious.
Causes of Gastric Cancer
1. Bad living habits <br/>Research shows that 80% to 90% of stomach cancer is caused by oneself, which is closely related to one’s own bad living habits. For example, people who smoke and drink for a long time, like to eat fried food, have irregular diet and other bad living habits are likely to suffer from stomach cancer.
2. Helicobacter pylori infection <br/>Helicobacter pylori is a carcinogenic factor, and the bacteria are directly related to many stomach diseases. Most people do not have obvious symptoms after infection, but it will cause inflammation of the gastric mucosa, gradually worsen the condition, and even lead to gastric cancer. Eradicating Helicobacter pylori can greatly reduce the incidence of gastric cancer.
3. Genetic factors <br/>Many diseases are caused by genetics, and gastric cancer is no exception. If you find that there is a gastric cancer patient in your family, the chance of developing gastric cancer will greatly increase, which is many times higher than that of ordinary people.
4. Environmental degradation <br/>Environmental damage, air, water, food safety and other issues are important factors leading to gastric cancer. If people live in such an environment for a long time, the chance of developing gastric cancer will also increase.
