Is gastric cancer hereditary

summary

A relative recently found gastric cancer. Her family is very worried about her condition. When they hear that it's a kind of cancer, they can't bear it immediately. At the same time, they are also worried about whether it will spread to the next generation. Because she is pregnant with a child, let me know whether gastric cancer is hereditary.

Is gastric cancer hereditary

First, it is generally believed that although the role of genetic factors in the pathogenesis of gastric cancer is not as important as that in colorectal cancer, the family history of gastric cancer may still be a risk factor. Because gastric cancer has a significant tendency of family aggregation, the incidence rate of family is 2~3 times higher than that of the general population.

Second, the familial inheritance of cancer is thought to be caused by chromosomal aberration, which is sometimes passed on to future generations. However, this kind of 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 can not eliminate the mutant cells in the embryonic stage in time, leading to the occurrence of gastric cancer.

Third: ABO blood group research shows that gastric cancer is related to type a blood, but only diffuse gastric cancer is related to it. Recently, with the application of molecular genetics in human cancer research, people gradually realize that cancer is the dominant role of activated cellular genes. In fact, it is caused by some gene mutations, which destroy the coordination of the control and regulation of normal cell growth and development, so that the role of cellular genetic factors in the etiology of human gastric cancer is more difficult, which needs to be further studied.

matters needing attention

This kind of situation will still exist, but don't worry too much. When you find problems, treat them actively, and then have children when the condition is stable. In this way, you can reduce the chance of heredity. You should also grasp your private life well. You can't touch alcohol and tobacco!
