Gastric cancer needs surgery in early stage, surgery combined with radiotherapy in middle stage, and palliative methods are mainly used in advanced stage. Gastric cancer is not easy to detect and diagnose in early stage, and the treatment is mainly radical surgery. Intermediate stage gastric cancer treatment mainly includes surgery combined with chemotherapy and radiotherapy, which can improve the treatment effect and reduce the probability of recurrence and metastasis. Advanced gastric cancer mainly adopts palliative treatment, because it is clinically considered that advanced gastric cancer is hard to be cured. The treatment goal is to control and progress the disease, reduce pain and improve the quality of life. Gastric cancer is important for high-risk groups to undergo gastroscopy screening on a regular basis for early detection of the disease. Due to the early clinical intervention of this disease, it can usually be cured. However, the treatment effect of progressive stomach cancer is poor, especially in the late stage. Therefore, after diagnosed with stomach cancer, one should go to a regular hospital to find a more specialized doctor to formulate treatment measures. The specific choice of treatment should be based on the dialectical guidance of the doctor in the face-to-face consultation.
