Is stomach cancer hereditary? It is possible

Diffuse gastric cancer may be inherited. Gastric cancer inheritance may be caused by chromosomal aberrations, which can be inherited.

Gastric cancer tends to cluster in families. Studies have shown that environmental factors are the main cause of gastric cancer, but heredity and immunity also play a role in the formation of gastric cancer. People with a family history of tumors usually suffer from gastric cancer due to environmental factors, but diffuse gastric cancer is closely related to heredity and is likely to be inherited.
The familial hereditary phenomenon of gastric cancer may be caused by chromosomal aberrations, which are likely to be passed on to offspring. However, this hereditary phenomenon does not directly lead to gastric cancer, but only means that individuals are more likely to develop gastric cancer. If the body's immune function is reduced or defective, the susceptibility to gastric cancer will increase. If the mutant cells cannot be eliminated in the cradle in time, gastric cancer is likely to occur.
