The time that cardia cancer can be maintained by eating and vomiting is not particularly specific, generally related to the patient’s condition, mentality and treatment. 1. Early pancreatic cancer, if the location is closer to esophagus, may cause congestion and edema due to tumor compression, and the patient’s food can not enter into the stomach smoothly, which will cause vomiting. At this time, the lumps are more concentrated and have not spread and metastasized, timely surgery can make the disease well treated and may not affect the life span. 2. In middle and late stage pancreatic cancer, when the tumor has spread and metastasized, it is usually difficult to operate, and timely radiotherapy and targeted drug therapy can prolong the patient’s survival period. Some patients may reach 5 years of survival, but if the condition is poorly controlled or the patient’s physical condition is poor, the survival time will be shorter. 3. Advanced pancreatic cancer is difficult to treat and due to the consumption of tumor, the patient’s physical condition is poorer, and the maintenance time may not be more than half a year. Cardia cancer should choose reasonable treatment plan according to specific condition under doctor’s guidance, and pay attention to psychological counseling with patients to enhance confidence.
