A lot of clinical data confirm that the offspring of patients with esophageal cancer in the family do not necessarily develop esophageal cancer. There are very few families with esophageal cancer in the world, about one-third of the members of such families 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 families of esophageal cancer are definitely related to heredity, but in fact, there are not many such families. It is gradually recognized through observation that lifestyle and exposure to certain carcinogens in the environment can increase the susceptibility of human 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.
