The number of years a patient can live with mid-stage gastric cancer depends on the pathological type of gastric cancer and the general condition of the patient, most of them can live about 2-5 years. At present, the main treatment method is surgical resection, after which radiotherapy, targeted drugs and traditional Chinese medicine can be combined to treat the cancer, and most patients can survive for 2-5 years after the above-mentioned comprehensive treatment. However, if the stomach cancer is of higher malignancy, such as Indolent cell carcinoma, it may only survive for about 1 year or even less than 1 year. If the malignancy of gastric cancer is not high and the patient is more sensitive to radiotherapy, the survival period will be longer, even more than 5 years. If diagnosed with mid-stage gastric cancer, it is recommended to consult oncology or gastrointestinal surgery and undergo radical surgery in time. The patient’s diet should be highly nutritious, soft and easy to digest, and should not be too hot so as not to cause bleeding.
