Is stomach cancer contagious?

The cause of gastric cancer is still unclear. It is not an infectious disease and cannot be transmitted through the respiratory tract, blood, etc. There is no genetic tendency for gastric cancer. Genetic tendency is an inevitable phenomenon, that is, if the father or mother is sick, the child will inevitably get sick. Gastric cancer only has the characteristics of high family incidence, that is, family clustering phenomenon and family history of gastric cancer. If a direct relative is a gastric cancer patient, the proportion of gastric cancer in his family members will be significantly higher than that of the normal population.

Usually, we should pay attention to a balanced diet, develop good eating habits, avoid spicy fried foods, avoid overeating or eating overheated foods, and avoid long-term heavy smoking, drinking and other bad habits. Gastric cancer is also related to diet. To prevent gastric cancer, the focus is on diet. The following measures should be taken:

1. In order to avoid eating rough food, those coarse grains that have not been finely processed, such as corn, sorghum and wheat, have hard shells and cause mechanical damage to the upper gastrointestinal mucosa. If protein and fat intake are insufficient, the damaged mucosa will not be repaired in time.

2. Eat less or no salted foods, salted fish, ham, bacon, etc., which contain a lot of salt and will damage the integrity of the gastric mucosa. If other carcinogens are present at the same time, it can promote the occurrence of gastric cancer.

3. Eat more fresh vegetables and fruits and drink more milk. Fresh vegetables, fruits and milk are rich in vitamins, which can help repair the body's natural disease prevention barrier and prevent the synthesis of chemical carcinogens in the body.
