Esophageal cancer is related to emotional excitement. The occurrence of malignant tumor must be closely related to the body’s immunity. Every cell division and every DNA replication may have residual products, but because of the immune system monitoring, if the cells have problems, they will be eliminated, or if the DNA has problems, they will be repaired, so as to ensure that the body does not suffer from tumor. However, if there is a problem with the immune system and the DNA is not repaired well, the cells will die, then it is possible that 1 cell or 2 cells will become cancerous and gradually grow into tumors. However, it must be a very long process from 1 cell cancer to grow into tumor. During this process, if the patient’s immunity cannot reach the normal state, his tumor will grow bigger and bigger until the immunity cannot destroy it. And anger happens to be a very direct cause of lowering immunity, but the negative emotional impact is a very long stage to be able to make the tumor develop.
