Gastric cancer also has a certain genetic tendency

There are many causes of gastric cancer. Many gastric cancer patients want to know whether gastric cancer is hereditary. So, is gastric cancer hereditary ? Let's take a look at the experts' answers.

Is gastric cancer hereditary? In addition to the environment and diet, family genetic factors cannot be ignored. It is understood that hereditary familial gastric cancer is a special type of gastric cancer. According to the diagnostic criteria of the International Gastric Cancer Association, hereditary familial gastric cancer refers to more than two gastric cancer patients in the same family, but the histopathology of gastric cancer is unclear; hereditary diffuse gastric cancer is a special type of familial gastric cancer. Its diagnostic criteria are more stringent, requiring at least two people in one or two generations to be sick, and at least one of them is under 50 years old when sick. The most important thing is that the pathological type of all patients is diffuse. Sometimes, several members of a family will get the same tumor at the same time, giving people the impression that tumor inheritance is a common phenomenon. Even if there are genetic susceptibility genes for tumors between relatives, different lifestyles and environments may avoid the occurrence of tumors.

Diffuse gastric cancer is closely related to heredity. Gastric cancer tends to cluster in families. Environmental factors may be the main cause of the occurrence and prevalence of gastric cancer, but heredity and immunity play a certain role in the formation of gastric cancer. The incidence of gastric cancer in people with a family history of tumors is greatly affected by environmental factors, and diffuse gastric cancer is closely related to the family. At present, gastric cancer is on a downward trend in many countries. The results of surveys and analyses show that intestinal gastric cancer is rapidly declining over time, while diffuse gastric cancer is declining slowly.

For high-risk groups of gastric cancer, early detection is required, and close clinical monitoring of healthy family members with hereditary and familial gastric cancer is required. The specific method is regular gastroscopy. Since the early lesions of hereditary diffuse gastric cancer are relatively hidden and often develop under the mucosa, regular gastroscopy must be emphasized, generally once every six months.
