The survival time of duodenal cancer patients may vary from several weeks to several months, and sometimes they can survive for a long period of time, which mainly depends on the severity of the disease, whether the patients can actively carry out the treatment, and their physical condition and other factors. If duodenal cancer is detected at a very early stage, radical resection of the tumor can be carried out, and chemotherapy, targeted drug therapy and traditional Chinese medicine therapy can be given at a later stage according to the pathological results. After follow-up, if there is no obvious tumor metastasis, then it is considered clinically cured, which does not have much effect on the survival period. If the tumor is found in a very advanced stage and the patient’s physical condition is too poor and not able to cooperate with the treatment, the survival time will be shorter. After the discovery of the disease, if the patient’s gastrointestinal tract can still be, can be appropriate intake of nutritious substances, in order to improve the body’s resistance, but also able to extend the survival time.
