Among malignant tumors, esophageal cancer has a large degree of malignancy and relatively poor prognosis. Early and middle stage esophageal cancer is usually treated by surgery first. If left untreated and allowed to develop naturally, it will bring more harm. What is the risk of surgical treatment? In one case, there may be metastasis and spread, locally, as the tumor further infiltrates into the esophageal wall, it may invade into the adjacent tissues and organs, such as near the aorta, if the tumor is connected with the aorta, we call it esophageal aortic fistula, once rupture occurs in this case, it will immediately cause the patient’s death. There is another kind of fistula which is close to bronchus and trachea and is connected to bronchus and trachea. For example, when the patient eats or drinks, part of it enters the stomach and another part goes to the lungs, and the patient coughs violently, and the lungs become infected, feverish, and even lead to lung abscess. There is another situation, although not connected to the organs, it can invade the adjacent tissues, the location of the esophagus is in the posterior mediastinum, in front of the spine is relatively close, once the external invasion can invade the tissue structure in front of the spine, this time the patient has such symptoms as chest and back pain. In other words, once the patient has symptoms, whether they are adjacent symptoms or choking symptoms, it means that the patient is a more advanced disease. Therefore, you can take ginsenoside RH2 during the surgery period, which can help improve the physical condition, increase the success rate of surgery, reduce the scope of surgery, speed up the healing of the incision after surgery, and prevent infection. It has the effect of preventing recurrence and metastasis, improving the quality of life and prolonging the life cycle.
