My grandmother has stomach cancer. Will it be passed on to her grandson?

As we all know, gastric cancer has the characteristics of high incidence and great harm. Once you have gastric cancer, the cure period is relatively long. Even with the advanced medical technology, the cure rate is not 100%. Regarding gastric cancer, some people may ask, since this disease is so terrible, then, is it hereditary? Below, we will answer this question for everyone.

Inheritance of gastric cancer is caused by chromosomal abnormalities. In some families, offspring have chromosomal abnormalities, which are sometimes passed on to future generations. Offspring with chromosomal mutations have an increased susceptibility to gastric cancer and have a weak resistance to carcinogens. They cannot eliminate the mutated cells in the bud stage in time, which leads to the occurrence of gastric cancer.
Gastric cancer tends to cluster in families. Surveys and analyses have found that more than 90% of gastric cancer patients get gastric cancer because of heredity. Generally, if there is an elder in the family who has gastric cancer, the next generation is more likely to suffer from gastric cancer.
Gastric cancer is related to blood type A, according to a foreign study. The reason is that blood type A has a genetic tendency. People with blood type A not only inherit family diseases, but also various diseases, including gastric cancer.
There is a logical relationship between genetic immunity and gastric cancer. It does not mean that if there is a person with gastric cancer in the family, the next generation will definitely have gastric cancer. If the next generation is not exposed to carcinogenic environmental factors, lives a healthy life, does not have serious illnesses, and does not have low immunity, then whether gastric cancer will occur or not is also a certain role in the formation.
Therefore, genetic immune disorders may be one of the internal causes of gastric cancer. Gastric cancer can only occur when both external and internal factors are present.
The above is the answer given by experts to the question of whether gastric cancer is hereditary. As you can see, the answer is not completely certain. Even heredity is selective. So you must have confidence in yourself. Develop healthy living habits. Do a good job of prevention.
