Is esophageal cancer hereditary? As we all know, esophageal cancer is one of the most serious malignant tumors and also one of the cancers with high incidence. Many experts have done research on whether esophageal cancer is hereditary or not. As far as the current situation is concerned, there is no unified conclusion on the heredity of esophageal cancer, and various experts generally believe that esophageal cancer does have a certain degree of family cohesion. The reason is that a family together, the food and eating habits they usually eat are basically the same. Esophageal cancer: genetics occupies a certain proportion. There is a certain family cohesiveness in the population with esophageal cancer incidence, for example, people from high incidence areas migrate to low incidence areas, but the incidence rate of this group of people still belongs to high compared with the local population, which can prove that genetics occupies a certain proportion. At present, it is believed that esophageal cancer is not a direct hereditary disease, but there is a tendency for the development of many esophageal cancers to gather in families, and if someone in the family has esophageal cancer, his children have several times more chances to develop esophageal cancer than the general population. These cancers are called hereditary familial cancers. The influence of such genetic factors is known as genetic susceptibility in medical science. It has been gradually recognized through observation that lifestyle and exposure to certain carcinogens in the environment can increase the susceptibility of the body to esophageal cancer. Certain patients with innate immune deficiencies have also been found to have a much higher risk of esophageal cancer than normal individuals. For hereditary familial esophageal cancer. Those who often have defective genes are more likely to develop esophageal cancer. A lot of clinical data confirm that the offspring of patients with esophageal cancer in the family do not necessarily suffer from esophageal cancer. In addition, there are very few families with esophageal cancer in the world. About one-third of the members of such a family suffer from esophageal cancer successively, and the incidence rate of men and women is the same, and they mostly suffer from the same kind of cancer, so such a family with esophageal cancer is definitely related to heredity, but in fact, there are not many such families. In general, genetic factors have a certain relationship with the cause of esophageal cancer, but it does not mean that as long as the elders suffer from esophageal cancer, the younger ones will definitely suffer from esophageal cancer. The genetic issue of esophageal cancer is very complicated, no matter what, it is most important for esophageal cancer patients to keep a positive attitude.
