Can father's stomach cancer be inherited?

Whether gastric cancer is hereditary is a question that I believe many people are concerned about. After all, gastric cancer has a very high incidence rate in our country. With this question, the editor consulted relevant experts. Now, in order to help everyone relieve their worries, the editor will give you a detailed introduction, whether gastric cancer is hereditary?

Patients and their families may not know this, but it is also a problem they are concerned about. The so-called inheritance, as the name suggests, refers to the transmission of genes so that offspring acquire the characteristics of their parents. Genetics is the discipline that studies this phenomenon. It is currently known that the existing life on Earth mainly uses DNA as genetic material. In addition to genetics, factors that determine biological characteristics include the environment and the interaction between the environment and genetics. Experts analyzed that if gastric cancer is hereditary, it should be transmitted by a certain gene in the cancer cells, and the cancer cells will undergo a transformation so that it can be inherited by the next generation.
So, since stomach cancer is related to heredity, can we conclude that the next generation of stomach cancer patients will all develop cancer? The answer is no. Why? Because human cells are divided into two categories: somatic cells and germ cells, such as muscle cells, bone cells, and nerve cells. There is no direct connection between the previous generation and the next generation. Only germ cells - sperm and egg cells - are cells that communicate genetic information between parents and children. When the DNA in the reproductive cells of the father and mother becomes cancerous, all cells in their children's bodies acquire this changed genetic information and may become cancerous. This is a "hereditary" cancer. The DNA of somatic cells changes in the acquired environment and becomes a cancer cell. Then the daughter cells generated by the division of this cell are still cancer cells. It will not affect the cancer of the DNA in the reproductive cells, so this cancer cell will not be inherited by the children. This is a "non-hereditary" cancer.
Not all stomach cancer is hereditary. People with a family history of stomach cancer should realize that although they may develop stomach cancer due to heredity, it does not mean that they will definitely get stomach cancer, and they should avoid unnecessary fear. On the other hand, they should pay more attention to cancer prevention and strive for early detection, early diagnosis and early treatment.
