Mesenchymal tumor of the gastrointestinal tract has a certain genetic background, but it does not mean that if a parent has gastrointestinal mesenchymal tumor, the child will definitely get mesenchymal tumor. In fact, not only gastrointestinal mesenchymal tumor, but also all diseases related to heredity, such as stomach cancer and intestinal cancer, just to say that it has some relationship with heredity. If a parent has such a disease, the likelihood of the child having the disease is higher than the average person, but it does not mean that the child will definitely get the disease. It is also possible that the disease is the result of a combination of genetic background and lifestyle and other acquired factors. Genetic background cannot be changed, but tumors can be prevented through a healthy lifestyle and more medical checkups.
