Whether gastric cancer can be cured in the middle and late stages depends on the situation, which is divided into two types: 1. Middle stage of gastric cancer: If it is the middle stage of gastric cancer, it can be cured through standardized anti-tumor treatment or comprehensive treatment mainly based on surgery, including chemotherapy, radiation therapy, targeted therapy, immunotherapy, nutritional symptomatic support therapy, etc. 2. Basically, it can only be cured through palliative symptomatic support treatment to prolong the survival time and improve the quality of survival, so that the patient can live more comfortably in the limited time. Of course, if gastric cancer is found, whether it is intermediate or advanced, it is recommended to go to a regular specialized hospital to find a professional physician to improve relevant examinations, such as abdominal CT, chest CT and whole-body bone scan, and if necessary, whole-body PET-CT can be done to clarify the stage of the disease.
