At present, it is considered that esophageal cancer is not a direct hereditary disease, but there are many cases of esophageal cancer with the trend of family aggregation. Some people in the family suffer from esophageal cancer, and the chances of children suffering from esophageal cancer are several times that of ordinary people. These cancers are called hereditary familial cancers. The influence of this genetic factor is called genetic susceptibility in medicine.
Through observation, people gradually realize that lifestyle and exposure to certain carcinogens in the environment can increase human susceptibility to esophageal cancer. It is also found that some patients with congenital immunodeficiency have a much higher risk of esophageal cancer than normal people. Hereditary familial esophageal cancer. People who often have defective genes are more likely to develop esophageal cancer. A large number of clinical data confirm that there are patients with esophageal cancer at home, and the offspring may not necessarily suffer from esophageal cancer.
In addition, very few esophageal cancer families have been found in the world. About one-third of the members of this family have suffered from esophageal cancer, with the same incidence rate for men and women, and most of them suffer from the same cancer. Such a family of esophageal cancer is definitely related to heredity, but in fact there are not many such families.
The genetic problem of esophageal cancer is very complicated. The occurrence of esophageal cancer is a mystery that has not been completely solved so far. Therefore, someone in the family has cancer and must not think about it. They should keep a happy mood, improve their immunity, learn and understand the knowledge about esophageal cancer, and help their families and friends to build confidence in overcoming cancer.
