Survival period of gastric cancer patients is related to factors such as tumor stage, patient’s physical condition and treatment. Gastric cancer belongs to malignant tumor of gastric mucosal epithelium and has a high incidence. Early gastric cancer patients have no obvious clinical symptoms, and some patients may experience nausea, vomiting and other symptoms. After radical resection through surgery, the survival period is about 5-10 years, and some patients can survive for a long time. Patients with advanced gastric cancer often show symptoms such as anemia, upper abdominal pain, decreased appetite and wasting, etc. If tumor invasion or metastasis occurs, the invaded or metastasized organs will also have obvious symptoms. Patients who can undergo surgery have a survival period of more than 1 year after comprehensive treatment; absolutely advanced patients who cannot undergo surgical resection have a survival period of less than 1 year, and some patients may have a survival period of several months. Patients with gastric cancer should visit the oncology department of regular hospitals in time, maintain an optimistic mood and actively cooperate with doctors for treatment.
