Is cardia cancer or gastric cancer contagious?

Cardiac cancer and gastric cancer are not contagious. They are diseases caused by multiple complex factors and are different from infectious diseases caused by bacterial and viral infections.

The occurrence of these cancers is usually related to unhealthy lifestyles, Helicobacter pylori infection, long-term stomach diseases and genetic factors. For example, although Helicobacter pylori infection does not cause infectious diseases, it is associated with the risk of stomach cancer. For cardia cancer, the risk is significantly increased in people with habits such as smoking, drinking and obesity.

Although cancer is not contagious, in daily life, some situations may be mistaken for "contagion" due to similarities in environment or living habits. For example, if a family eats too much greasy food, pickled food, or smokes together, it increases the possibility of stomach cancer. So, instead of worrying about "contagion", it is better to start by changing your living habits.

In order to reduce the risk of cancer, it is best to have regular physical examinations, especially if you have symptoms such as stomach discomfort, loss of appetite, and sudden weight loss, you should consult a doctor in time. At the same time, you should eat a light diet with less salt, reduce pickled and smoked foods, pay attention to quitting smoking and limiting alcohol, and maintain a proper weight to reduce the burden on the stomach and stay away from the threat of such diseases.
