Is it likely that my grandfather will inherit stomach cancer?

Is there a high chance of inheriting stomach cancer from my grandfather? Stomach cancer has become a disease that seriously threatens human health in today's society, and it ranks first among various cancers. It can be seen that the harm of stomach cancer is so great. So many people will ask whether the harm can be inherited to the next generation? Let's discuss this issue next.

1. Gastric cancer inheritance is caused by chromosomal aberration. It is currently believed that the familial inheritance of cancer may be caused by chromosomal aberration. This chromosomal aberration is sometimes inherited by offspring, but this inheritance is not a direct cancer inheritance, but an individual's tendency to develop cancer. When the body's immune function is low or defective, it can increase the susceptibility to gastric cancer, and the mutant cells cannot be eliminated in the bud stage in time, leading to gastric cancer. People with type A blood are more likely to develop gastric cancer. Studies on ABO blood types have shown that gastric cancer is related to type A blood, but only to diffuse gastric cancer. Correa reported that 49% of 164 cases of diffuse gastric cancer were type A blood, accounting for 38.3%. The connection between diffuse gastric cancer and type A blood is a genetic tendency.

2. Recently, with the application of molecular genetics in human cancer research, people have gradually realized that cancer is the dominant effect of activated cell genes. This is essentially caused by some gene mutations, which destroy the coordination of controlling and regulating normal cell growth and development, leading to abnormal cell reproduction. However, it is difficult to study the role of genetic factors in the etiology of human gastric cancer, and further research is needed. Genetic immunity and gastric cancer Epidemiological studies of gastric cancer suggest that environmental factors may be the main cause of the occurrence and prevalence of gastric cancer, and genetics and immunity also play a role in the formation of gastric cancer. In 1980, Correa divided gastritis into autoimmune, hypersecretory and environmental types from an epidemiological perspective.

Is gastric cancer hereditary? Although the disease is hereditary, the chance of inheritance is very small. Therefore, only timely treatment of gastric cancer and keeping a relaxed mood will play a better role in the treatment of gastric cancer.
